Rear end gearing

What headers do you run? I would spend $150 and have that converter cut open and checked out while you have the trans out.
It has the pro parts headers on it, same as the old McCandless headers.
From what i remember the bell housing is very tight coming out from between them.
Wish i knew if it was the trans or the converter , the converter would be easier , as i think i could pull the trans back far enough to get it out.
I think this is an ATI also, have to go see if I can find the info. The guy I got it from said it had 1 free check up. I wonder if he still has the paperwork from it.
