I NEED A DECODER RING

ok, so yesterday I bought an 85 t/a and now I need a littlee help decoding the it. attached is a list of all the codes and what I have found for them so far. I think some of them are wrong and apply to a different year due to the numbers after the description. And some I have no information on. I tried using the decoder on here, but didn't find any new information. If anyone has any info on any of them please help me fill in the blanks. Thanks

Re: I NEED A DECODER RING

ok, thanks. That filled in the last couple ones. turns out they were just some sales program and a paint color. but then, I already knew the inportant ones. WS6, J65, GW6 and M35. Now it's time to build a new motor.
