[70BLAZERX2]

Yes 3.42 posi...but its the gov-lock...thats coming out..and a 91-96 caprice/roadmaster posi unit going in...same spline..and its the auburn clutch type posi...I have one in my 94 truck..it.does awesome..

11 rear drums and rear swaybar...

Z56 option..is there ...police brakes. (3/4) ton calipers..on 1/2 spindles..

370 pads instead of a 369 pad..

Rear is going in the 99 soon...The little brakes on the rear suck for towing...gm should have went disc on there models long ago..

I tried the 2000 ecm in the 99 and it would not even start? Is this because of the vin in the ecm?

I had 2 97 trucks here and swapped and it runs fine...?
