Speaking of A/C - I think I now have enough W123 cars that need A/C repair to learn to do it myself.
If I step away from Harbor Freight and get better quality gauges and vacuum, what brands/sources/retailers would be a good place to start. Regarding the vacuum, I have an 80 gallon Champion compressor - are air -assisted Venturi pump vacs worthwhile or should I go electric? I won't say money is no object but I prefer to buy quality when it makes sense.
