Going: Feel like I am looking into a long lost tomb or a nuclear fallout shelter Gone: Never removed the evaporator case before. The bottom case rear fastener was a pain to get to. Did not want to gorilla or cut the case out Out with the old in with the new Replacing the factory ac with Vintage Air IV Gen Sure Fit. Original plan was to replace only the engine compartment factory freon. Pricing everything, cost ranged from $1,000 to $1,400. Went looking for options and it was VA. Knew nothing of VA but had read some about in on the forum. Very impressive for pretty much the same price as only the factory freon in the engine compartment, getting a complete new system designed for 134a, more efficient. In addition, will get something that actually fits. Before buying read the VA 28 page installation pdf and watched a YT of one going into a 81 Camaro. Emailed questions to VA. Pretty much a tab a into slot b with no special tools or technical knowledge needed. Felt comfortable parting with the cash and doing it myself. Two amps have to move to the trunk: Not enough room in the glove box area with the new ac install Something else missing: While removing the factory ac, decided to remove the radiator core support for some metal work. Good shape overall but two areas (not to large) have weak metal. Monday, will take it to a couple of shops for options. Get it done now of never. Even it the work costs more than a repro, don't want a repro for what I have read on the forum their fit is not that good. So fix the original.
