Frustration w/ AC on '91 Old'* 98
Shader valve on the low pressure ac line stripped out over the weekend while doing some work on system. Went to junk yard and pulled a new hose line from a '93 and was excited to get it for only $12.00......everything was going great, matching up just fine then I went to screw the line onto the condesor inlet........problem......new line connection was larger than old line. Tried to find a reducer/increasor at several hardward stores.....NO luck. I could go and pull the condensor as well......extra work.....or go back to the yard and try to find the right app. Any thoughts anybody? I wanted to scream at GM for making that slight change between '91 & '93. The system on the '92 was R-12 and the '93 was 134-A but that doesn't look like it would make great difference..............every job I do takes 2 days longer than planned!!!

The line changes were specifically because of the R12 to 134a change. Randman and I ran into that on the Frankenbonne project.
You have two choices. You can change the whole setup over to the 134a system sizes and convert or find a correct year or pre 134a car and get that line.

That line had to come from a 94, GM did not use R134A on the C and H bodies untill 94.... Alll 93 and earlier models used R12...
And just as it was stated, the fittings are very diffrent for that reason..
