Oldsmobile's initial A-Body entry was known as the F-85. While that name alone may not be recognizable, checking the right boxes on your F-85 order sheet would've given you several better-known variations such as the Cutlass, Vista Cruiser, or 4-4-2. One box you couldn't check on the order sheet was LS Swap, but our swap systems can help you out with that.
