Well Zip had a good point about spacer length, but all the ones I've ever ordered appeared to be the same length....

Who made your gearset? When I ordered my ring and pinion from Richmond, I ordered the big bearing installation kit as well from Richmond...and all the bearings, shims, gaskets, pinion spacer, etc... came with it.

You can order the spacer by itself from Jegs...part #: 836-04-0011-S

It's the very same one that I ordered when I swapped cogs in my Mustang GT 8.8". In fact, the description says it fits both 8.8" and 9" Fords...so I'd say you'd be fine with it.

There's a lot of guys on here with a ton more knowledge than I have...but if it were me, I'd just order a new pinion spacer, shove it between the bearings, press it all back together on the pinion...then check your pinion depth and backlash. I honestly don't think you'd have a problem with it...but like I said, I'm not the sharpest knife in the drawer.

Hope this helps.
