i didn't say the "rears" were 8 3/4 these were ford 9's and dana 60's most wouldn't even really try to talk to me about building me a 8 3/4. said thay a x brand would be better and the 8 3/4 was a weak rear for a 500 HP motor!!!!
They need to get out of the business an 8 3/4 properly built(thats probably the problem they don't know how to build one) can handle 500 plus h.p. no problem....
