I have a 1970 Trans Am subframe in my shop. I was going to sell it for about $300 but then it crossed my mind to check out the steering gear box. The part # is 5691676. The stamp on the saginaw plate is 098 0. I know the 0 on the right means 1970. I don't know what the 098 means. I read it's a build date? maybe August the 9th? I read it's a fast ratio 14.5-11.1 and 2.5 turns lock to lock. The pitman arm and all the steering linkage, a arms, springs, front disc brakes is there also. I also read that the spindles are unique to the 1970? Anyway, Is there a special demand in this hobby for a 1970 T/A gear box and/or complete subframe? Thanks for any advice
