I can get the mount that bolts to the engine, it’s the frame mount that I’m having trouble with. I have the Chevy 305 frame mount and need the olds

As stated any Olds powered Gbody frame mounts, plenty of 307's being pulled for LS swaps find someone doing that and they will probably give all the mounts for the price of shipping.

Any 260, 307, 350 frame pads will work. I haven't done mine yet, but it allegedly has them already.

There are dual pattern TH350. The one in my 70 was a long with a 85 TH350C that came out of a Caprice, so they exist old and newer. Make sure it is beefed up machined for the extra direct clutch, better sprag and Transgo shift kit that dual feeds. Any 73-90 RWD motor mounts will work once you get the corresponding frame mounts. Also replace the stock, soft spider gears in the 7.5" rear, they like to explode.

Going from the 305 to 455 I already know that the battery needs to be moved from the passenger to the drivers side to be closer to starter and alternator... the engine I bought came with everything from radiator to bell housing. The ac on the 455 is on the passenger side and is the long style. It was taken off the engine when I bought it but they left the brackets on the engine. Trying to get a game plan together for that while I’m pulling the engine apart on the stand. Would I need to source the hoses from a 78 with a olds engine? Wondering the chances of the 78 accessories bolting up to the 455 brackets?

From what I’m guessing from the casting numbers is that the 455 was built on the 15th day of 1971 in Linden, NJ?? ... if google is correct, the only 2 body styles of Olds built there were the Toronado and 98. It does have the G heads.

455 in my 79 cutlass factory air hooked up stock mounts used, was a 260 car 307 mounts and pads should be the same and work perfectly

Pretty sure all G bodies came with the R4 compressors. You could get a modern Sanden compressor that fits the old style brackets with custom lines to fit your car.

The 200 & 229 V6's used the A6 compressor. I chucked mine about 25 years ago.
