Body mount and lift install questions

[77K20]

I have a 77 K20. It has a 350ci, 4-speed, NP205. I have it down to the frame right now and I am getting ready to put a cab off my 77 C20 on. I bought an Energy Suspension polyurethane body mount kit, and a Performance Accessories 2in body lift kit. I hate body lifts, but it was necessary in order for the 2wd cab to clear the t-case. Anyway, what should I know, have ready, be prepared for, etc. when I begin to put things back together? I am mostly concerned with the body lift. Are there going to be any clearence issuses as far as the steering column, or clutch linkage or anything like that? The instructions for the body lift say I have to weld an extension to the clutch rod. Where does this go exactly? Any advice, tips, tricks, or whatever that you have that might help me is appreciated.

You couldn't cut the hump out of the 4wd cab and screw it into the 2wd cab?
You'll have fan shroud clerance issues, also watch the radiator hoses. for the clutch rod you'll need to disconnect it and once you get the cab on and lift in you can see what you need to lengthen/correct it. When I swapped mine over I had to remove a home made body lift, I also had to fix the clutch linkeage, the guy had changed the geometry by changing the pivot point under the dash. What a pita! the steering column should extend.

I suppose I could have cut out the floor pan and tried to make that work, but I don't like the idea of cuttin up my truck. Especially if I mess up somewhere, I don't have the skill to make it right. I figured a body lift would be less hassle and less nerve racking than taking the sawz-all to my truck. I have a pretty good idea what I need to do with the clutch, but I am sure it will become more obvious when I start to put things back together. So steering won't be an issue? Just curious, looking at your sig, why do you have different gearing for the front and back?

Like Jim said, you will have to adjust for the rad being higher. You can move the rad down, but this can be a pain and hard to get mounted correctly. You can also cut the bottom out of the shroud or move the shroud down, but then you will end up with less airflow and possible cooling problems. I ended up going down to the junkyard and pulling an electric fan out of a Ford Torus. I wired it up to a switch in my cab. Works great as long as you remember to turn it on.

As for the clutch linkage, I just used a piece of all-thread in place of the original linkage rod. I just used 2 nuts to lock the correct length. It's fully adjustable too, works great.

Steering should be fine. You'll have to extend the steering shaft. It's adjustable but might be stuck in place (mine was).

Nothing wrong with body lifts if installed correcltly. You should be fine.
