Since you have green floors and the cover is white.
Ah, great detective work, ha ha. It's coming back to me now, I just wish I had the old pics to confirm, I think this truck came with no trans cover, so you are right the green floors do not match the cover as I went out and bought it.

So since the cover comes off, it must have been a manual truck, now I don't recall seeing a third pedal, but that may have been replaced. And now that I think about it, I did remove a do dad off the driver side frame by the transmission where I think a Z bar mounted to shift the manual trans, I will try and find that thing and post it on here for further confirmation. Which leads me to believe the steering column must have also been replaced as it now has an auto shifter lever on it... great!

Once again I really appreciate you droppin' all that 411, it really helps, I am still learning this Gen and it is by far my favorite Gen of trucks. (Sorry Rusty and Busty)
