Supercharge SSE
 

what happen too that Supercharge 88-91 white SSE. Is it run ok now....
That is the Clean looking SSE on the planet. Do that guy have any pictures of the finsh product..... Will the SSE become a collect car..... Will this car gain Value.....
Also my rear Brakes lockup sometime..

Search "frankenbonne" and you'll find it. It's up and running.

Get your brakes looked at. I'm not sure why just the rears would lock up.

Sounds like your rear brake cylinders are leaking. A bad cylinder leaks fluid and causes the shoes to go bad prematuraly (causing lock-ups).
BTW, does your ABS take over if they lock up?
Could also be a bad proportioning valve, but the wheel cylinders are cheaper I believe (under $15 per side) and they are pretty easy to change as long as there isn't too much rust/corrosion.

Try this on for size...and definately search under Frankenbonne...Frank and Formerly 97
