81 Turbo T/A with 400 what A/C stuff works?
My '81 Turbo Trans Am has had it's 301 Turbo engine replaced with a '76 400 engine.
Unfortunately whoever did the swap also deleted all A/C parts. I don't know if he did this just to get rid of the heavy A/C parts or because all the 301 Turbo brackets and so on don't fit onto the 400 engine. What I want to know is from what donorcar can I get the A/C components like compressor, brackets, lines etc. I suppose 403 olds T/A 'parts don't work How about 301 (non Turbo) parts? Will the A/C stuf form, say a late '70s 301 LeMans/Grand Prix/Catalina work? I 'd like to get everything off of one car. I do still have a late model short A/C compressor (I think a leftover from a '96 LT1 T/A) but I don't think it'll work. Any advice on what to get and what NOT to get? There aren't many 400T/A's in junkyards here in Europe (read; none), and shipping this heavy stuff from the US will kill me, so I need to find other ways to get my A/C back

The attached photos show the Ac parts for a 79 TA. The two hose assembly on the compressor is the same for a Pontiac 400 and a Olds. 403 engine.
I would recomend converting to a Sanden compressor and staying with R12. Vintage Air offers a bracket for mounting a Sanden comperssor on a Pontiac engine. Part number 141001-PPA. Ebay Item number: 150258872627 is for the accumulator. Ebay Item number: 140237476427 is for the 79-81 Trans Am A/C hose set.

All of the AC brackets from the 301 fit except the one that bolts in the rear of the compressor to the intake manifold due to the different deck height. I have been running one without it for several years that was my kids daily driver to school. The 301s rotary compressor works fine also and is smaller than the earlier A6 ones. The turbo car in 81 had the accumulator near the radiator vs on the evaporator core like the no Turbo cars. You can do it either way depending on the lines available. The turbo lines were not available stil here when mine cracked so I had to have a custom one made-not a big deal though.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
