Panel bond?

[JDMopar]

3M or Fusor panel bond is pretty expensive stuff to use for seam sealer. I'd put that hump in just like you do when you convert an automatic Mopar to a 4 speed. Trace around it with a Sharpie, then remove it and trace another line an inch or so inside the outer one and cut it on that line. Then you will have plenty of a ledge to weld to. I have always used 3M Fast n Firm seam sealer and never had a problem.

If that bondo is pretty thick on the back of the cab, it should turn loose if you heat it with a propane torch. You should be able to scrape it right out with a putty knife and not have to deal with so much dust from grinding.

That's pretty much what I'm doing here, going from an automatic to a 5 speed...... still granny 1st, like the 4 speeds used in these 3/4 ton trucks, but add an OD on top of that...

I cut the hump in using out of a 90 club cab at the local junkyard by my house with a battery powered Milwaukee angle grinder... And cut it plenty wide. Gonna trim that down a bit before I set it in and do the sharpie thing. I went above the pinch weld that separates the floor from the firewall.....

Well today i ground off and drilled 66 pop rivets and ground off all the Bondo with a battery powered Milwaukee 4-1/2 angle grinder and a cup wire brush. Add 21 holes for Bondo to bite into that were drilled and I have a mess.
they did very randomly tack weld it here and there.
They welded it pretty solid from the top end of the ribs to the bottom of the window opening. And that doesn't actually look too terrible. I dressed that with a flapper sanding disc on the angle grinder. I may overlay that with another pass. The very top of the cab wall has gaps on either side of the pinch weld at bottom of the window opening. The kid that my son got the cab from did tell my kid that he had a hard time keeping the back window from falling out... It did so while the cab was on my trailer before I got out of the driveway from the barn it's been stored in, I pulled it out the the rest of the way out so it wouldn't fall out and bust into a gazillion pieces.
I did switch the 0.035 spool out of my MIG, replaced it with 0.023". I swapped out the drive roll and contact tips as well ... So that's ready

I've never personally had the back window out of one of those cabs, but I do remember that it is a rubber gasket window instead of a glue in window. Check and see if they got the lower lip too short or something when they put the back of the cab back on it. It should probably be straight across too, so see if they got it weebly wobbly or something. If I remember right, those cabs have a pinch weld all the way around the rear window opening, and the gasket has a channel that fits onto that pinch weld to hold it in place. Might have to get a new gasket if they screwed that old one up. Sounds like you're making pretty good progress on it.

If you are in the same zone Fastenal blue line freight is a cheaper alternate form of shipping if you decide to get the other cab that doesn't need sweat equity. Good luck Don

I didn't think they'd haul something that big..I've.used.fastenal shipping before
I have only 6 hours away. I have one in my sights and I was.all ready to leave straight from work last Friday but they never called me back like they said they would. Only about 6 hours away by Paducah

 

[jeff alder]

perfect...I'd do the trek. Wren lake and Shawnee are nice make a mini vacation out of it!

 

[volaredon]

Still holding out hope the idiots in Paducah call me like they said they would.
Failing that, has anyone here ever done lead/solder for body filler? Like Gene Winfield would have done ... Id like to put a layer of that over the seams as opposed to old standby, Bondo. I've sweated alot of copper pipe over the years I wonder how much different doing the same to sheet metal (steel) might be. It would definitely be more water tight than Bondo ever was.

I know people who have used aluma lead years ago to do this. I have never used it, but I know Mike Kohl had his Grandfather Jim Spinola used it when he built his 64 1/2 2plus 2 Mustang. Jim was an expert Union glazer, and they used Aluma lead where the rear quarters and roof line met etcetera. I don't know if you ever saw this car Don but it was a 64 1/2 2 plus 2 Mustang painted by Sonny Brammer. It was silver loaded with flake and had a hand panted cobra snake on the hood ready to strike. 289 302 boss head built to the hilt with a slap 4 gear. Narrowed Ford 9 inch with some really phat Mickey Thompsons. They built the building on 4th and main in Watseka and their glass shop and muscle car shop was in that building. His little brother (My age) had the copper with white top 67 coupe Barracuda built by Merton up there in your Kankakee area. The preacher's son thru a lit book of matches in the Mustang which ignited an Angora sweater Mike's wife had sitting in the front seat. The car was destroyed. The body panel work by Mikes grandfather was flawless totally undetectable and watertight. The fire melted it out of the seams. I would not have remembered this except I remember old Jim commenting on how fine his work was that only a fire could kill it. He was in his 80's on crutches when they did the body.

Bummer. Not a surprise.
