The low-side pressures aren't too bad, but the high side is far too high, pointing to a condensing problem.
I would attack this problem from two fronts:
1. Replace the fan, check that nothing is obstructing airflow through the condenser, and that all foam seals and shrouds are in place. (The water ...

Re: High side line blowing off
Springlock Connectors aren't reliable IMHO, but they ARE cheap, appealing to corporate "bean counters." Instead of replacing the lines again, a clamp as described in the previous post helps solve the problem of the connector suddenly coming apart under pressure.

Re: 2004 F-150 Heritage AC
I was afraid that you might not be able to remove the compressor with the studs in the way.
The oil is a question mark. If you can't get it all in the compressor, you'll have to "oil-balance" the system--that is, ~1.5 ounces in the evaporator, ~1.5 ounces in the condenser, ~1.5 ounces in the R/D or ...

Re: High hi side pressure 400psi
If, say, the ambient temperature is 65°F, then the low side and high side should read about 30/160 PSI respectively.

Re: 2004 F-150 Heritage AC
An induction heater sounds like a good idea, or an acetylene torch if it's safe to use.
Alternatively, can you get a die grinder in there to grind-off the bolt heads and then use a set of locking pliers to remove the studs after the compressor is out?

Re: Blows cold but gauges read equal
Confused about a few things in your post. That said, is 125 PSI the static pressure (engine off, compressor disengaged) that you're reading on the low and high sides?

Re: High hi side pressure 400psi
Have the refrigerant recovered, and then remove the liquid line at the TXV. If you find desiccant beads, then the R/D has disintegrated.

Re: Sourcing R12 240sx compressor
Did you call Tim at ACKits.com to discuss? He might be able to help you.
Why not convert the system to R-134a rather than keeping it R-12, which is extremely expensive and hard to find?

Re: STRANGE ISSUE NEED HELP!
First thing I'd do, as already suggested, is to recover the charge and see what it weighs. If it's low, the system probably has a leak somewhere.
The high pressure seems a bit low to me, further suggesting a low charge.
I'd look up the specs for you, but I'm traveling outside the USA right now and ...

Re: 2008 Tundra strange (to me) issue
If you're charging by pressures instead of by weight, you've most likely overcharged the system, causing the safety valve to vent refrigerant.
