I'm looking to replace the old drum brake rear in my 88 camaro with a disc brake rear end from an 86 T/A Firehawk. It's in the local junkyard. I want to know if it has posi or not. This car does not have the RPO's cause it's been gutted. Any help is appreciated. Thanks, Paul M

 

Not "all" third gen disc rears were posi.

86 T/A Firehawk?????

 

If you can physicaly lay your hands on the rear, simply give one of the rotors a twist. If the other rotor rotates in the same direction it's a posi, if it moves in the opposite direction it's an open dif. No need for RPO codes on this one.

What is an 86 T/A Firehawk?

btw my 84 Z28 has a disk rear but no posi

 

I believe that the Firehawk is a limited production edition. It has the rear disc brakes with the 5.0L HO V8. It also has the WS6 package with a 30mm(I think) front swaybar and the thick one in the rear. It also came with the P245/55/R15 tires.

 

Actually, the front swaybars are way bigger than 30mm. Don't know the exact spec though.

 

First Firehawk was 91-92. Someone is full of ****.
