9 Speed Shimano Feehub Spacers put on a Screw on Freewheel?
Would this fit? If it did this could turn a 7 speed freewheel into an 8?

I doubt it. Freewheels (FW/FWs) usually have two different diameter spacers. There are 8spd FWs available though.

Still don't really understand what you're asking.
But, though 8 speed (or even 9 speed) freewheels are available, you can't just put them on your existing 7-speed wheel.
1: an 8 or 9 speed freewheel is deeper than an 8 speed, requiring more space on the rear axle. You'd have to re-space the axle and rebuild the wheel.
2: 8 and 9 speed freewheels are a bad idea because they move the cogs too far outboard of the bearings in the hub. This leads to the axle breaking eventually.
7 speed freewheels are cheap, dependable, and easily changed out. And they're all the same size so they're interchangeable. If you want more than 7 cogs, you have to use a cassette hub instead. They go to 11.

AFAIK going to a freewheel of different width only requires redishing, not rebuilding.
I am not set on more than 7 cogs, less wheel dish with 7 cogs would be of benefit enough.

There are 9 speed freewheels too. My hubs/axles are meant for 7 speed, so I'm sticking with 7.
If you want to keep the Campy Record freewheel hubs but reduce dish, then look for a rim with off-center spoke holes. The off-center holes negate a bit of the offset of the hub (for the freewheel).
I recently built up wheels on some old Phil Wood freewheel hubs. That hub's flanges are 5mm offset to the left. The off-center rim is offset 4mm back to the right, so it resulted in only 1mm of dish. Nice strong wheels.

I cannot find info on the Phil Wood hubs mentioned?

Mine are Phil Wood "Road" hubs from ~1997. The ARR630 is probably their closest equivalent. Go to this page and you can see all their different hub options. Their cassette hubs are way expensive, though.
