Ac swap troubles.

[SilvyLightning]

Just swapped the 305 tbi outta my 90 for a 87 vette motor.
Well the vette motor has a 93 silverados ac compressor.

I had to go to a pick and pull and snip off the harness connector for it as my 1990 connector was different

However the issue I'm having is with the ac lines bolting up with those washer seals on there

There's a little gap on one of them. Do you guys think I need to swap the lines and accumulator to a 93 for it to work?

I believe I had the terrible r4 compressor and this is a upgrade

I think they make one thick and one that's thin
I had the same problem on my grand national

If you put some pics up of the compressor and a close up of the fitting issue i'm sure we can help more. I am thinking you have a harrison(delco) variant, there were a few different ones other than the R4 back then so pics would help identify it. Regardless, the thicker seals should be easy to come by; my AC Delco new R4 came with them in the kit.

Okay I'll post pictures tomorrow. When I attempt to bolt on the ac lines using the washers that's there it seems to me like the right one(yellow plastic on it) is to thick or large for the hole. It sits a little crooked so I'm sure it would leak.

But I'll snap a few photos in the morning

This isn't the photo I got of it.

Any insight? I don't see why I couldn't go to a pick n pull. Snip the little harness connector I need for it and grab a accumulator and lineset for the compressor

If you look at the ports on the back of your compressor, you'll see that the sealing surface is at a different depth on each port. They each take a different thickness sealing washer. Take a look at this document to get you pointed in the right direction.

That's still the infamous R4 compressor, just with a different port configuration.

Do you know the port configuration?

I assume Autozone may have my sealing washers, they had replacement ones for my year, make and model.

As far as I can tell. The accumulator, lines and condensing radiator is all factory.

I don't, I was just saying the configuration that you have requires the thicker seals, which should not be hard to obtain at all. Autozone should have them.
