As the previous owner of this car let me clarify a few details...
I installed 4th Gen seats, shifter and console in the car. The transmission tunnel has been modified to accept a 4th Gen shifter and console. The way it is right now you cannot put a 3rd Gen shifter back into the car the way that it sits. Also, the plug for the power driver's seat has been cut and now has a plug for a 4th Gen power seat (which worked great when I owned the car). The rear is a 9-bolt posi with 3.27 gears (the car had a 2.77 originally). The driver's side wheel cylinder leaked when I drove it last. It has sat for over a year so I am not sure if it was fixed or not.
The rear area above the gas tank has been cut so that you can get to the fuel pump without dropping the rearend. It also had a brand new Holley FP installed. The car was originally a TPI car. I put an LT1 into the car and the fuel lines have been modified for an LT1 along with the wiring harness. It should have braided fuel lines as well.
The rear suspension should still have BMR LCA's and a Hotchkiss panhard bar along with a custom STB out front. It has good hatch struts too.
The car is a very solid car and was originally from California and Alaska for most of its' life. I went through and fixed the leaks from thr T-tops so it should be nice and dry. Finally, I installed a '91-'92 Z28 spoiler out back so the car does not have a TA spoiler.
It's a heck of a deal for $700 especially if you are looking at an LT1 conversion.
Later,
