<<Years ago my wife had a Bronco 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>>

You gotta be Benny Hinn and performed a miracle with this 134 on top of
the mineral oil, no evac, no o-rings, no dryer change.

PTL & Hallelujah.

What did you slap the hood of the Bronco with the palm of your hand when
you were all done ?

Heal !!
