I think your front suspension should swap easily. IIRC, the front springs are the same, but the 3/4T has a beefier axle. The rear part of the 3/4T frame is parallel, unlike the 1/2T which is tapered from front to back. Since you are using a different axle, you'll have to mod the perches to fit your truck anyway.


Current fleet (subject to change w/o notice)
\'49 GMC 3/4-Ton , 60 Austin Healey Frog-eye Sprite (some assembly required), 2011 Dodge Avenger, 2015 Jeep Cherokee. No, they don't all run.
My other ride is a (B737)no, (B767)no, A320.... Update... was Embraer E190, now Boeing B787.

Knowledge is a wonderful thing, but ignorance means you don't know you can't do something.
