8.75 chunk

[moparnut]

just curious is the yoke on all 8.75 chunks swapable?for instance if you bought one with a small yoke and needed a big yoke or visa versa do they both fit?which yoke is common on e bodies?
thanks

no , there are 2 splines 10 & 29 so youi need to check the size of the nut , 1 1/4 " is 10 spline , 29 is 1 5/16 or bigger

thanks Chryco,whats more common on E bodies?

Looks like the 489 posi chunk i bought on Epay a year ago has a 1-1/4 nut and the one on my GC has a 1-1/18 nut,Would these be the same spline count?So could i just swap the yoke from the one in the car to the Posi Chunk?
thanks

possibly itr will work , if they are 489 carriers they have a crush sleeve & retorquing the nut you need to be very careful retorqueing the nut so you get enough brg preload without over crushing the sleeve

[moparnut]

so what are the best questions to ask someone when buying a chunk?and which one is the best?
thanks

well I prefer the 742 carrier , & find one with a yolk the size you need , or pay a low enough price to replace the crush sleeve with a spacer
