I dont have an 8 3/4 end.. ive got the 7 1/4 on right now. Im on the search for that 8 3/4 don't get me wrong now. Not looking to blow anything up.
The KH's on ebay defientely need rebuilt. They are the 5x4" pattern however. Theyre at $200 but have $106 of shipping to add.
IF i can get them for $200 shipped, hemi71vx is willing to rebuild them for me. Of course at an expense. All in all.. i should be into these breaks easily $500- $600 range.
