My 69 GP SJ has these numbers stamped on the rear pumkin cover,
8058 on a round circle stamped on the right side if the rear pumkin cover on the lower left side.
Below that are these numbers 8975082.

Do I have a Posi or Peg Leg. Anyone know the gear ratio ??

Cowl Read
ST69 27675
TR 298 89 B PNT
24 2J

I AM FAIRLY SURE IT'S BRUNT ORANGE METALLIC ??

iNTAKE mANIFOLD #'S ARE 9794284 WHICH I THINK MEANS 428 ENGINE & 4 BBL

VIN # IS 276579P240752 ???

ANY HELP WOULD BE GREATLY

THANKS

Not sure about numbers stamped on the pumpkin cover, but there should be some cast into the housing. Easy check for posi is get both rear wheels in the air and see if they spin in park, if they go opposite directions its open.

Will a 1970ish Pontiac 350 bolt into a 64 Grand Prix 4speed. What needs to be done? Thank you.

Anything is possible, for sure a motor mount change would be required. Running the original 4 speed?
