need help with 73 firebird ac parts

73formula on Tue May 05, 2009 10:32 PM User is offline

Year: 1973
Make: pontiac
Model: firebird
Engine Size: 400
Refrigerant Type: r12

Looking to contact Chick regarding a/c questions. I reside in NJ and Jack mentioned I might want to contact you. Would like to contact you by phone if possible. I need firewall forward components and have located parts from a 1975 but it has a VIR. Could you assist me in the best possible route o get the a/c working again and possible local vendors if needed for hoses etc...

Thanks
Ken 732.604.1338

Sorry, I’ve been pretty busy, first, is this car going to be for shows where points will count? If so, you need to leave it stock. If not, there is nothing wrong with the VIR system. Tim (Ackits.com) sells the VIR rebuild kit which comes with a new desiccant if you want to retrofit, but will also work fine with R12 (my choice for that car) Is the 73 and 75 the same generation car? I can‘t remember them all.. .. If so you might need the evaporator too, since I believe the 73 used a drier and expansion valve along with the POA valve? Not sure.. That would make the fittings on the evap different.. So using the one from the 75 is the easiest.. As far as the compressor, let me e-mail Tim to ask him a question and I’ll get back to you.. I see from your area code you are down the shore? I am up by the Lincoln tunnel, and getting hoses rebuilt up here is not easy, and very expensive, I would suggest once you know which way you are going with your project you get everything together and ship them to Ackits (Arizona mobile air) and this time of the season I’m sure in shop turn around will be fast, and reasonable, not to mention excellent work.. Another month, and it might take much longer as they swing into their busy season.. Let me know which way you decide to go, and post it, a lot of guys here have excellent knowledge of both systems.. Hope this helps..

Mr. Chick, its 100 plus here so we are already swamped. We need to get you a Mastercool 71550 and some welding rod along with a few weld on adapters. You could make a killing (for a retired guy) on making up hose sets.

Thanks for the reply...I just had a 1973 condensor shipped from a yard and now am considering ordering hoses online for the compressor w/muffler, the drier jumper line and the liquid a/c line. I am not sure if this is all I need though since I don't have the originals to look at where they go. The jumper line from the poa is there(the curved line coming out of the firewall attaching to the poa) as well as poa and expansion valve.

Do you think I need any other lines and what should I do to clean the system since the end of the poa and expansion valve fittings were left open for years? Also, can you tell me a cheap place to charge his thing with r-12 or should I buy it online(i have the r-12 can filling hose from years back)?

Thanks
