frank I already have converted my front A/C to R134A using the original
condenser. It works fine and blows cold but in my opinion is still
inadequate when the temp starts going up. Since the compressor is capable
of putting out somewhere in the range of 40,000 BTU it only makes sense to
me to make maximum use of it and go with the larger condenser.

But to make this work correctly (or even the stock one) you have to make
some basic changes in the electrical wiring.

There is to much current flowing thru the drivers side A/C switch in the
dash and the wiring going to the condenser fans is undersized also. Both of
those are easily taken care of by using Bosch relays to "trigger" new
wiring to both the fans in the evaporator and the condenser.

I am convinced that if you make this change and go with the larger
condenser you will get the cold air you need from the chassis A/C that you
need under the worse conditions. Seems like a very small cost to me for
such a large pay off.

We are lucky to have the forward control coaches in that the chassis air
can be truly made to work. The PT models on the other hand have such long
runs of A/C lines that even under the very best conditions they are
inadequate. For those I would defineatly change to the 6260 or even larger.
