1990 Suburban

[rack]

Hello guys,
First of all, thanks for the great forum!
My name is Ivo, I live in Sofia, Bulgaria.
Let me show you my 1990 Suburban and plans I have for it.
It is 1990 Chevy Suburban, 4x4, TH400, 5,7 TBI, 241C transfer case.
Friend of mine inspected it and bought it for me in June 2012 from Atlanta and I got it here in September 2012. I think I have great luck finding this Sub. It is very clean and rust free, original condition with normal wear for the years. The engine and tranny runs fine.
Here are some pictures of it:




What I have done so far:
Changed spark plugs, spark plug wires, distributor cap and rotor, temperature sender, blown exhaust manifold gasket on driver side, engine oil and filter, air filter.

My plans are to install LPG (propane) system as soon as possible. I got all the parts I need, just waiting for weather to get warmer here.

What I have to do and need some advices on are:
Change weather strip on all doors because the rubber is hard as rock.
I have bought kit including all weather strip and seals needed.

There are some leaks around the doors, the carpet is wet, I also see drips inside around drivers door, see on the picture, the head liner is not wet. First I thought it leak from roof rack holes, so I removed it and seal the holes, but it did not stop the leak.



Do you think the leaks are from bad door seals?

About the roof rack, I want to keep it on, but there are 3 huts pull out. Is there any easy fix that do not require welding?

I will really appreciate your help and advices.
I will post my progress on the project.
Best regards,
Ivo
