I checked the alternator earlier and it's 37A, so I will match up the regulator. The car has A/C but is missing the compressor, guess they needed to replace the alternator at some point and elected to go with the 37A. When I finally get to putting a compressor back on I'll have to look at changing out the other componets. For now Im just itching to get it tagged and enjoy before winter. I'll let everyone know how things go...Since this is my first 1st Gen after years of wishing I am sure to have more questions as I correct little details here and there
