I have a 1976 Buick Electra, and...after replacing my VIR Receiver dryer thingy (long story short, they only used them from 73 to 76-and apparently won't work well with R134) found out I'm leaking behind it, in the evaporator. So many companies out there ( and Rock Auto doesn't sell the VIR replacement, but they don't sell evaporators either, only repair kits for them) the cheap ones, typically with part #6513PFC are like $70 to $133 and say they fit 76 to 86 Buicks (some also say universal) https://www.ebay.com/sch/i.html?_from=R40&_trksid=p2047675.m570.l1313&_nkw=6513PFC+&_sacat=0 the ones 3X more expensive have part # ev6220 and look to fit both full sized cars, and Regals, Camaros... https://www.ebay.com/sch/i.html?_from=R40&_nkw=EV6220&_sacat=0&_sop=16 anyone know ...anything about these? Are many the same in all GMs of the 70s? I did notice the more expensive ones show the tiny 3rd tube (not even sure how they are connected, doesn't show in pics) thanks!
