The '71 and '72 K5 I had that leaf spring "stop" bracket too...I still have one in my parts heap somewhere I think...
I read somewhere it was supposed to help keep the axle from moving back enough to cause a kickback in the steering...maybe an old Chiltons book I have?..I never understood why they didn't put one on both sides?...
I left mine on one truck,maybe thats why it never stopped in a straight line?..--the other truck I took it off because it only had one bolt that was loose holding it on...

Your engine might have a rats nest or a pile of nut shells in a cylinder,if it sat that long...we started up some engines at the junkyard that sat a long time and some sounded like a bearing was pounding BAD--tearing the heads off revealed a rats nest,nut shells or chunks of carbon that broke off that were getting smashed against the piston & head...some ran fine after removing the offending material!..

I kinda wondered about that because it did sound kinda like a piece of carbon in the cylinder, not really a hard "rod" knock but not a slower, valve-related knock either.
There was a bunch of hickory nut shells around the air filter too. But, I pulled the valve cover off the passenger side and at least one push rod end was mushroomed on the end. The rocker was flopping so I tightened it down some but the knock persisted.

Also poured some ATF thru the carb while it was running, sometimes that will help dislodge and expel carbon chunks.

I also found a bunch of empty oil bottles too when I was cleaning the inside ......not a good sign. There's some, but not a lot of oil around the rear main seal.

I don't know, I ain't gonna tear into the motor right now anyway. I'm gonna start with the body I think. Get it braced up and off the frame. The motor will be a lot easier to work on, or replace then!

Damn this winter!.....it's still cold here and my barn ain't got any heat!
So progress was slow tonight but I managed to get some stuff off.
Outer cowl panel, front bumper, all fender bolts came out easily and 1 radiator support came out easy.

I have the perfect tool for getting the stubborn ones out!

Draining the anti-freeze and getting ready to pull the front end off.
The weather girl says it will be warmer this weekend.

Woot!
My hats off to you winter guys with no heaters, making progress is tough enough without things freezing.

I have one of those tools also. Must be nice to have a lift in the garage.

 

[A1971Blazer]

I had intentions of restoring a '79 ford F250 4X4 and had a lot of stuff gathered up (still got some)!
Anyway, putting the lift in was a necessity for me.
I think I posted it before.....I'm too old to crawl around on the floor under a vehicle!

It just makes it so much easier to persue this hobby!

NEVER scrap any of your old "scrap" metal.
I dug out enough to start fabbing up a temporary tow bar so I can move this thing around with my tractor.
Still cold here so I had to quit early tonight.

The AC compressor looks suspiciously like a York, so hang onto that and its associated bracketry (I'm thinking it's dealer-installed or aftermarket.) That also looks like the large diameter pulley which I believe to be less common, fwiw.

Those compressors are popular for onboard air, so even if you don't want it you could recoup some $$ selling it to somebody who'd want it for a wheeling rig.

It is in fact a York, just not sure what kind of shape it's in? There was an aftermarket AC unit installed at some point in the life of this rig but the freon charge was all gone when I removed the pressure lines.

I'm looking at a system fron OldAir to go back on and posibly switch back to a factory style compressor. Just not sure yet what engine I will be using when it all starts to go back together?

On my Jeep, I was using the Harrison pancake style that was on the tuned port motor for my on-board air. I machined a manifold with a drip oiler sysytem to lube it but without the oil circulating in the refrigerant, it didn't last long. I was thinking of fabbing a bracket and putting the york on it? Kilby has all the brackets and stuff too. I like the yorks because of the crankcase style oiling. They pump much faster than the electric ones. I always carried an impact wrench in my tool box and used it MANY times!
