I found this good deal on a posi unit from an 94 impala, and I know that there has been talk about being able to swap units from impala's into a 8.5 10 bolt rear end from the C10. I don't know what years from but my question is, if it will fit into a 1984 chevy C10 with the 5X5 axles and do they come with 31 splines as same as the impalas?
IIRC you have a 28 spline axle and the imp has the 30 spline.
Damn, i knew there would be something different. Well were could i find a posi unit that would fit my application, any other interchangeable posi units that would work.
Just buy a new trutrac or valutrac from Rons, he is a site sponsor on here. Look in the sponsor section for his link.
yeah that would be easy but I'm more on the budget side. $400 and up is a little steep. I don't mind going to the yards and digging for one just want to be sure i pull it off the right vehicle.
Weld up spider gears. Cost bought 20 bucks :)
+1...that 10 bolts gunna blow sooner or later might as well not put too much $$$ into itQuote:

i hate to say it but if your not going to go aftermarket upgrade id leave the one tire fire. instead of the grenade 80. the g 80 will just cost you more money down the road

+1 for the trutrac. the valutrac is not offered for 28spline axles only 30spline. build it right or dont do anything. being cheap will have you spending more later. the 8.5 will take some abuse if set up corectly.
Well sounds like the best way is to build it with the trutrac, sounds about right about spending more the easy way out.
why not swap a whole impala rear end in or in my case i swapped a whole 12 bolt out a 70 1/2 ton into mine i paid 200 bucks for 12 bolt with 4.11 gears and a factory rebuilt posi unit.
