small to big 8 3/4 bolt pattern

for an a body 8 3/4 ???? where do i find morons like that , I've got one I'm selling to a friend I'll sell for 2k :toothy10:
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!!!!
