I have an 86' Gl-10 4x4 that has a blown headgasket and seized engine, I want to get the thing up and running again because I love driving it, but I also wanted to look at doing an EJ swap instead, what type of Ej is going to be the most straightforward for the swap, I want to keep my 5 speed in it, although I know I'll have to swap out the 4x4 hi/lo 5spd trans for a newer awd manual trans, what kind of tips and advice can you all offer? Thanks for whatever help I get!

I'm sad to say now my trouble is just finding the transmission, does anyone know a good place to get them from, or to get my trans rebuilt at in the greater seattle area?

So I have a 86' GL-10 with 355k on the body, I'm not sure of the mileage on the transmission, but it's starting to be extremely rough shifting all gears, and sometimes doesn't like to go into first unless I'm at a complete stop, how difficult is it to replace the transmission myself on the 5sp 4wd version. I've done a trans swap on a 2001 Camaro, but that was rwd. I guess tied to that would be asking if there is anyone in the greater seattle area that would be able to do it for me, obviously for a price. I plan on driving the car cross country in May with some friends so I'm trying to get it into shape for that. I've replaced everything short of the radiator(perfect condition), trans(shifts hella rough), engine(makes a ticking noise while idling, if sitting for more than 5 minutes, also burns some oil when using trans to decelerate) and diff(seals on rear diff are slightly leaky but 4wd works solidly) at this point.
