Hi guys – I would appreciate some feedback on my sure-grip replacement.
Need a replacement differentialunit for the 8.75” 489 rear – 3.23 R&P (yes that’s what I want in there) in my 67 Barracuda
Not planning on (serious) racing, maybe a little light hopping and I do like the curves!
Just wondering, which might be abetter idea for me:
