Replacement Fork for 27" Fuji Gran Tourer SE

I'm trying to get a replacement fork for my bike and wanted to double check what I should be looking for.

Wheel Size: 27 x 1-1/4"
Dropout Width: ~4" (100mm)
Brake Hole to Dropout: ~15"
Steerer Length: ~7-1/2" (190mm)
OD Steerer @ Crown: 27mm
ID Steerer: 22mm
(I tried to upload and insert pictures but it said I don't have permission to post url's?)

I read somewhere about ISO vs JIS for the ID of the Crown Race. I'm assuming this is JIS because it's an old Fuji and the OD or the steerer at the crown looks to be 27mm? Is this important?

I'm wondering if any of these forks will work:
amazon.com/Sunlite-Threaded-120mm-Thread-Length/dp/B007HOMANM/
amazon.com/Sunlite-Threaded-LW-Thread-Length/dp/B003VFCDEM/
amazon.com/Sunlite-Threaded-LW-Thread-Length/dp/B00629PTGI/
amazon.com/Sunlite-Threaded-length-Chrome-Non-Canti/dp/B0014C639K/

Or is it better to get something like these on Ebay:
ebay.com/itm/NOS-Vintage-Road-Bike-Fork-1-Threaded-27-Steel-Tange-5D-Orange-Japan/201917938725

The first or last forks listed should be very close. The second has no steerer length info in the ad and the third is for the wrong wheel size. Personally I would avoid any used forks.

27mm is a very common crown race seat diameter for Asian bikes of moderate cost. Matching this dimension is very important if you don't want to replace the headset too.

BTW the steerer ID is nominally 22.2. The 22.0 ID is the classic French steerer ID. Andy

Hmm, yea I guess I'm not sure if I should get this orange Ebay fork, which I feel like is a sure bet for size after looking more closely:
ebay.com/itm/NOS-Vintage-Road-Bike-Fork-1-Threaded-27-Steel-Tange-5D-Orange-Japan/201917938725

Or get a new one with the chrome Sunlite:
amazon.com/Sunlite-Threaded-length-Chrome-Non-Canti/dp/B0014C639K/

I don't understand what all these dimensions are for the Sunlite:
LW 27 Threaded 1 (7/8 ID) 200mm Caliper Hi-Tensile Chrome 50mm 399mm 27mm 3/8 100mm

Is the steerer length 200mm, 399mm, 100mm?

Also if I'm worried about my old crown race not fitting the Sunlite, is this what I would need to replace it?

"I don't understand what all these dimensions are for the Sunlite:
LW 27 Threaded 1 (7/8 ID) 200mm Caliper Hi-Tensile Chrome 50mm 399mm 27mm 3/8 100mm"

LW- light weight- advertising BS
Threaded 1- Steerer is a 1" OD threaded (and presumably 24TPI)
(7/8 ID)- the steerer's internal diameter is 7/8" or 22.2mm
Caliper- No canti or disk mounts and with caliper brake mounting hole
Hi Tensile- Material, high tension steel (as in not 4130 or Reynolds)
Chrome- The finish, chrome plated
50mm- I assume the rake as 50mm is within a common range
399mm- The axle center to crown seat dimension (and a 27" rim has a 315mm rim bead seat radius, virtually the same as the rim's brake track radius. Subtract the crown seat {about8 to 13mm usually** and you have the caliper reach)
27mm- The crown race seat diameter
3/8- Presumably the drop out slot width, as in how big in diameter an axle will fit
100mm- presumably the length of the threading at the top of the steerer (A headset needs around 25mm min. of thread unless spacers or other stuff in between the threaded race and the lock nut

That an on line listing has so much description is a very impressive thing. Far more then the typical eBay info you often see. Andy

This is the black version. https://www.amazon.com/Sunlite-Threa...dp/B003VFCDEM/ If you are going to paint it, get the black one, put a layer of light gray primer over the black if you are planning on a lighter final color.
