Re: [T3] A/C

["Shad Laws" <shad@lnengineering.com>]

Hello-

Toby - I was about to make a big reply to Jim's statement, but you said it
all :-).

I've done a couple custom A/C systems for aircooled VWs with excellent
success.  Wrote an article about it in VW Trends a few years ago, too.  My
T3 has A/C on it, and I would _never_ have it any other way.  Of course, it
has the modern compressor, etc. etc.

Take care,
