I have a 84 6.2 square body with A/C but I can't decide to keep this compressor or get a short smaller one like on the early 6.5. Is there any advantages to the longer one?

Ok so my main question is which one gets colder lol? I don't care about real estate, thats not why I wanna change it, just want the one that works better.I wouldn't willingly put a early 6.5 POS R4 "pancake" compressor on anything. Keep what you got or use the suggested even better Sanden 507 because it's light years better than the R4 leakmaster grenade. The R4 was a POS even with the low head pressures and better oil flow of R12. The only way I get a R4 to live beyond the miserable 2 year warranty is to evac and charge the system every year and run alternate refrigerant.
do ya mean swap brackets from a 96+? i have the complete 96 engine in the shop now with all brackets. would anything else need changing?We really don't have the room on a 1993 to drop in a longer compressor. Swap the accessories brackets to a 96+ with the AC on driver side and maybe.
is this info the same for my 93? i'm gonna want to get it going eventually and want to copy if it applies.
i have everything that was bolted to the engine, except PS pump.Yes. Need longer AC hoses - have them made. You have the altonator? Check the clearence on the t stat to AC. The tensioner is critical as the 1993 spring has to take the compressor load where the 1996+ doesn't and is a weaker spring.
Quick question - I can't get the blower to kick on and it looks like it was replaced not long ago. (Truck was last on road in 2008 lol) But anyways I THINK its the control head because the sliders feel pretty loose. Checked with a multimeter and we have voltage to the relay under the hood. Had to run a direct wire from a/c compressor to battery to charge the system. Blows cold air out the floor vent but whenever I use the sliders on the control head nothing changes.You can run the sanden on the 93, but you have to move it furthur out to clear things. To swap to the 96+, you have to change all the accesories, tstat housing, hoses, try to clear the throttle bracket, and all that. Then you have the infamous belly leaker compressor. The harrison radial compressors aren't horrible, but they just are not holding up anymore.
