We need to install a factory AC unit on our 1969 Buick GS 400. A gentleman has a complete front clip with all parts from a 1969 Buick Skylark CUSTOM. Is everything the same from a 1969 Buick Skylark Custom (350) to a 1969 Buick GS 400?? Brackets the same? Etc??? Can we use that unit and upgrade to R134?? HELP!!!!!!
I have found that most of the brackets, at least the giant aluminum ones, are FOR SURE the same from BBB and SBB. I also beleive some of the pulleys are the same, but they were stolen off my parts car by a Buick fan.
most of the stuff will work. Some of the A/C lines may not be long enough as the front of a 350 sits further back than the front of a 400. Also, you can contact board member "nickbuickgs" for additional help ... you can upgrade to 134a but you need to go through the complete procedure replacing seals, flushing ...etc.
Agreed ... but you better have a good friend with a nice bottle of R12. Nothing blows like 12 - I've got 43* of cool blowing out the vents of Sporty
I have 2 articles on the site below showing the AC brkts differences. You will need the correct upper triangular brkt that goes over the valve cover and the correct ac/alt arm. Everything else will work.
