Reporting back. The SN95 springs worked out great. They look almost identical but drop the car to a nice front stance. Glad I don't have to do that job again anytime soon!
I used springs from a 98 V8 GT all around on my car. With aluminum heads the front dropped a little over an inch.
I started with a stock 87' Tbird 5.0 (dished piston) low mile block.
