Years ago my wif had a Broco II with NO freon in it.and I changed the
fittings to the 134 style and just filled it up with 134 instead of the R12
it came with....no oil change, no evac, just filled it..
Worked great for 3 yrs till it sold...no issues whatsoever...so it can be
done, just needs a tight system or other than a van system I guess...Daryl
