Exa-drive 8 speed wheel modernization
I got an unused campy 8 speed wheelset with an exa drive freehub body built on open pro's for a good price thinking I could put a newer freehub body for 10 speed on it that I had sitting around and dish the wheel. When I pulled the old freehub off and went to put the new one in, the part where the pawls is larger than the old and therefore I can't install it. Does anyone know if there is a modern freehub (shimano or campy as I haven't got the rest of the drive train yet) that can be installed on those wheels to modernize them? I was looking at these by miche, which look like the diameter of the pawls is smaller.
Does anyone have any experience with modernizing these older hubs? Thank you.

I think you are going to have to resign yourself to enjoying your 8-speed wheel. 8-speed Record cassettes come up on eBay. I found some really nice 8-speed Record Ergoshifters from a guy in France. But down-tube friction shifters work very well with 8-speed setups too. The apex of Campy's development for us ordinary guys was their 8-speed groups. They are the B-52s of Ergo: pretty soon the stuff will be older than the guys riding it, and still going strong.

not all campagnolo 8spd hubs can be updated to 10spd. i am not experienced in the update, but it sounds like you are out of luck.
like others posted, campy 8spd is great stuff and lasts forever. we actually just built up a bike with NOS 8spd derailleurs, crankset, bb, and a used wheelset. we didnt have any 8spd shifters, but dia-compe's micro ratchet levers work great with it.

When I pulled the old freehub off and went to put the new one in, the part where the pawls is larger than the old and therefore I can't install it.
Lighter but not as attractive as the older 8 speed hubs (Campagnolo reached their aesthetic pinnacle in the C-Record era and retained it through the first generation ergo gruppos).
Does anyone know if there is a modern freehub (shimano or campy as I haven't got the rest of the drive train yet) that can be installed on those wheels to modernize them?
1997-1998 Record and Chorus, 1998-1999 Athena and Veloce have 10mm steel axles and freehubs with the 9/10/11 spline speed pattern. 2000 Veloce hubs have a different axle/bearing setup and will not swap.
They also use a CS201 (12 and larger first position) or CS301 (11t) lock ring with a 26x1mm thread instead of the newer 27x1mm standard or older 29x1mm 8 speed lock ring.
New freehubs disappeared about 10 years ago; so you'll probably have to buy an appropriate used hub, swap freehubs, and sell the left overs.
It'll have have conventional sized lock nut + cone wrench flats on the non-drive side and aluminum freehub body. Avoid Record Titanium and Alloy 8 speed hubs which use a slightly different spline pattern
A single wide bolt flat is a cartridge bearing hub (all 2000 and newer non-oversized hubs, some older hubs below Veloce) with a different freehub that won't swap.
The large 3-sided nut with a pinch bolt goes with an over-sized axle and one of two different incompatible freehubs.

Starting with new 9 (rounded hood ergo levers, the 1997 pointy hooded levers still use v1 ergo internals which have mostly been discontinued) or 10 speed (perhaps 2010 levers, last of 10 speed Ultrashift and without the weak detents from 2009. I bought a pair of 2010 Centaur carbon levers before the supply runs out) are better ideas for parts availability.
When you import your nickel plates cassettes from the UK 10 speed cassettes can still be found for under $40.

Yes, even though 13-26 is out of stock at Ribble, 26T cogs last a long time and could be moved onto successive new 13-23 cassettes, no? (removing one of the middle cogs of course.)

No, they just take different parts.
The rear derailleur pivots wear out (and new 9/10 speed with tension adjustment on the cage have a different pull ratio so they don't interchange. OTOH, some people do get 50K miles out of a derailleur), the right shifter springs (discontinued apart from the G-springs) wear out, the right shifter G-spring carriers crack (discontinued), and Campagnolo discontinued most of the 8 speed cassette variants. The hub bearings are good for decades though.
Starting with new 9 (rounded hood ergo levers, the 1997 pointy hooded levers still use v1 ergo internals which have mostly been discontinued) or 10 speed (perhaps 2010 levers, last of 10 speed Ultrashift and without the weak detents from 2009.

what i should have said was 8spd campy is very durable. we have 3 bikes in our family that run 8spd campagnolo and they still perform great. in this time, we have gone through shimano 8, shimano 9, and campagnolo 10 and in my experience the campagnolo 8 will outlast them all.
i have heard people talk about the g sping carriers cracking, but i have not seen it. i recently converted a set of 8spd record titanium levers to 10spd and they shift fantastic. i would say they are a little crisper than normal (non red) record 10 levers. if the spring carrier were to crack on these i would be heart broken.
is it possible to fit the 10spd g-spring carrier to fit an 8spd lever? the only difference i can recall is an extra rearward facing tab on the 10spd for the rear "coil spring". without seeing the parts side by side, i think a little dremel work could make it work.

It's an easy swap to update any steel axle 8 sp Chorus and below to 10 sp. Xenon, Mirage, Veloce, Athena and Chorus all used the same steel cassette hub body. I did the upgrade for about $75 in parts a few years ago. You need to have the wheel redished though. If you can't find the cassette hub anymore just buy an old Veloce/Mirage 10 sp hub for about $35 new on ebay. In retrospect, it would have been cheaper to just buy the entire hub than the cassette hub body. That way you get spare ball bearings axle and skewer. Good luck.

So the newer mirage freehubs will fit? How old is older? For example, is this one likely to fit?: https://cgi.ebay.com/CAMPAGNOLO-MIRAG...item5d2d009762
Thanks,

10 speed Hub, lace up another wheel, enjoy paying a lot more for all the spare parts, in the future..
8 speed chains are comparatively Cheap.

Khamsins are $175 https://www.totalcycling.com/index.ph...urrency&id=USD
Scirocco's are under $400 https://www.amazon.com/Campagnolo-Sci.../dp/B001N89VAI
You can't make wheels as good as those for the price. Good luck
