I measured over 12” from the carrier housing made my mark and then measured from that mark my 2 7/8 section that I wanted to remove. My total measurement was 17 1/4 from the housing to where the brake plate and caliber brackets mount. In a nutshell I made drivers side housing length the same as the passenger. As far as bearings go...I just went to Rockauto and looked up what I needed, copied the part number and then EBay or Amazon for the parts so I could get the free shipping. They do make C-clip eliminators for these and they start around $160...I read on an explorer forum that you wouldn’t need them if your rear has Disk Brakes...however NHRA will not allow you to run a stock rear if you’re in the 10.99 (1/4mile) or 6.99(1/8mile) brackets.
