AC work (that time of year) - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Well to the point, putting a 400 small block in my 69 GMC 1 ton flat bed with a serpentine kit which uses the smaller AC compressor. I want to clean up the rest of the engine compartment and get rid of the POA system. I seem to recall about 3-4,5? years ago an article in here---YES I SEARCHED-- about pulling the box apart and installing an OLDS? evaporator and using a receiver/dryer along with an expansion valve and 134a. Anybody recall this? I even printed it out but have lost it.

There was a good one in the FAQ as I recall.

Got a link? I couldn't find it--- I looked for just about an hour

Here are a couple of old links:

Also you do know you can get R12 compressors for a serp setup.
Mine came off a 96 9C1 Caprice.

The post by bobbyk is the one I remember and neon larry has posted a link to it above. That was a good thread.

Thankfully I didn't have that problem when I installed my new A/C in my '63 a couple months ago. It was a nice, clean install.
