No floor mount shifter, classic column type. I've never seen a floor shift on a 91 (not saying it didn't happen)
It looks like there is room for it but I prefer the column type.

I just went out to the car and grabbed my spare cover. Looks like I've got a F79 = 2.97 and I've confirmed the trans model is a 4T60 the 4T60-E started in March 1991 (Got the info from my local tranny shop)
This is a big help, Thx jr's3800!! cause the RPO code thing was 100% clear until now.
I did a search from google and found a complete GM RPO code list in a PDF file. What a score !
I have a way to find out what'* in the caddies now. I'm so happy :·)
