I've been looking for a disk-brake rear for my 89 Formula for awile. I have located one in a parted-out 89 IROC. The car is complete except for the doors, motor, d/s front fender and interior i think. It still has the rear, wheels, and 700R4 tranny and i assume the rest of the body.

What would be a reasonable offer for this car?? Also, does anyone know what gear ratio options were available for the 89 IROC / disk brake / 700R4 combo?

89 Formula Black / Grey cloth int...305 TBI / 700R4 auto...Borg-Warner 9-bolt 2.77...rear disk brakes...Nitto NT450 tires...K&N Filter...Flowmaster Crossflow...Accel cap/rotor...Accel Supercoil

 

anyone?

 

wheels, tranny, body (what shape?), and rear end. Maybe $500?
I got my parts car for $700, 1987 iroc-z, for comparison it had:
tpi 305-running good
700r4-great shape
2.73 posi
rims
leather interior
bad front clip

I will attempt at the gearing;
305 5 speed-3.42
305 auto-2.73 and maybe 3.42? (only sure on 2.73)
305 auto-3.27 (borg warner 9 bolt)
350 auto-3.27 (borg warner 9 bolt)
350 auto-3.23? 10 bolt
There are probobly more that i don't know. To my knowledge these were available.
Sorry if this isn't quite right, I'm sure someone will correct me.
