i got an 86 and would like to know what kind of rear end i have and what the gears are and if it is posi or not. thanks

Well if it's the original,it would be a corporate 10-bolt 7 1/2 ring gear. As far as posi and gear size goes,you need to see what the "G" codes are on your option label in your glove box.

G80-posi (if no G80 listed,than no posi)

GU1- 2.41
GH2-2.29
GM8-2.56
GU2-2.73
GU4-3.08
GT4-3.73

thanks for the help

The rear end gearing depended on the engine. The LB4 4.3L V6's got 2.56 as a standard rear end. If you have a 4.3L V6 and the G92 "Performance Ratio" option, it's a 2.73 rear end. The LG4 5.0L V8's got 2.41 as a standard rear end. If you have a 5.0L V8 and the G92 "Performance Ratio" option, it's a 3.08 rear end. These were the only four rear ends offered in the 5th generation El Camino.

Let us know what you have.

it came with the 5.0. i don't know what package it came with. i'll have to run the vin and find out.

The VIN will not tell you what rear end you have. Look at the option label in the glove box. If there is a G92 code on it you have a 3.08 rear, if there is not a G92 code then you have a 2.41 rear.

Your gonna confuse the poor boy. 8O I think I made it much easier for him :P

I have a set of 3.08:1 gears out of my 80 SS, they are in good shape if anyone locally wants them they are free. I won't ship them anywhere. I had planned to throw them away I just haven't gotten around to it yet.
