OTT = On The Tree, 3 on the tree, the shifter for your 3 speed is on the steering column.
POP = Protect O Plate, it's a small metal data plate(about the size of a business card) that is usually attached to the owners manual, last page. It has the vin #, engine#, trans# etc.. But without it you can't match the trans or engine numbers to the vin.
Your trans should be stamped on the machined surface just below the side cover, drivers side. But it really could be anywhere on a machined surface. They got stamped in lots of places. Even GM found it tough to keep track.
