Hey folks, I've been lurking around here for awhile, doing searches and hunting down as much info as I could about 1st generation Troopers, since I picked one up for the whopping sum of $400 to replace my 73 Suburban as a daily driver.
This Trooper showed signs of having head gasket problems early, so after I'd looked around here, I managed to pick up a 3.4 for the Troop, figuring to swap it in later, when a good chance showed up.

Well, it seems like there's NEVER a good time, as the head gasket problem resurfaced last week, and I have to drive to California in two and a half weeks, so it's engine swap time!

I'd PM'ed Ed Mc, and he sent all the swap info he'd accumulated (Thanks Ed!), but a couple questions. Everything I read mentions dropping the front axle center section by undoing 4 bolts. What size are these? Nobody mentions that. Having the bare bones in metric tools, if there's something I need, I'd sure like to know.

Also, I picked up a 4.3 throttle body w/injectors, and all the plugs match the 2.8... is this a trick? LOL! I haven't quite understood the posts on this, as it seems like everybody has a slightly different throttle body.

Enough for now, I can see eyes glazing over...but thanks in advance for any advice and/or help, and how come there's so many Isuzu guys in Washington?
