A/C for your 58
I live in Phoenix,got to have A/C! You can do this cheap,I did for less than $150 in my 65 Pickup.Since this is a Vintage truck you might check ebay for an underdash unit from a Chev with the retro emblems if not wrecking yard units here run around $35, next it will be easier if you get the compressor and brackets and pulleys all from the same vehicle and the matching water pump.The hoses you can get from a local A/C supplier,be sure to get a new drier from them too,you can get a 134a conversion from Auto zone but first you need to to evavacuate all the old R12 from your Wrecking yard finds before you install the 134 kit,then charge it up,and BE COOL!
