straightaxle

I just bought a 92 4x4..the frame where the control arms go is completely rusted...i have a 85 straight axle i bought new, it has been a tough truck and was built in japan..they say the straightaxles are better....i was wondering if this could be done fairly easy...these are both regular cabs..the only thing is that i am missing the doors for the 92 model, i can try and find some of them cheap....was wondering if can be done, the problems i will run into , and is it worth it.....my 85 has serious rust issues but run and operates like a champ....around the windshield i have black urathaned it to stop the leaks that i have around the windshield.... if it can not be done waht about the bed....i hate to part with this truck, i have a new chevy hd2500 duramax and rather drive my 85 beater.....any input will help out alot....i pretty much know these trucks ....but is this worth it......trying to save my truck.....the 92 i sold the engine it only had 67k on it ...what i have been seeing is that the 22r carb last longer than the 22re fuel injected.......someone said that i could take the 85 axle and weld it in the 92...sounds like alot of trouble to me....what would you pros do in this case.....hope you can encourage me to do the correct thing......please email me back.....also can email me at blown@comcast.net....thanks jeff
