5 ton crew build

[CrappiePoint]

After a lot of research I’m going to begin an m923 crew cab build. I have a donor cab ready and after checking out a bunch of builds decide on suicide doors. I have a lot of experience building and fixing all things mechanical but this will be the biggest build I have started. I will post pics from the build so folks can follow along and help me figure out roadblocks if they choose to. I’m not going to mess with the donor cab floor. I’m going to follow Plan B’s advice and fab a subfloor to an extra horseshoe cab mount in the back. We are big folks so I’m adding some extra room in the cab for air ride seats and legroom. I will add some pics and we will kick this pig!!!!

Holy **** , there's a name i haven't seen in >30 years.

Bugtussle.

We had a guy in Basic from there. The little worm ran 2 miles in 10:46. I can't for the life of me remember his name.

We bought 2 tankers from them when they upgraded to HETs. Its a cool name, so we are going to ask if we can keep it crest on the doors.

IDK what they went with. I am going off of memory and have not seen them in person.

Got some good work in yesterday. Removed the exhaust and intake stacks. Watch out for the lines on the intake stack. The grab handles were the worst of the bolts, they will strip the heads if you’re not careful. Took the top off and shop vac ‘d the floor. Next step will be to cut the back wall off the truck cab at the jambs and in front the c channel on the back cab mount.

Had a couple hours and got the back off the original cab. But also found the floor was rotten to the trans hatch!!! All of the tacks that hold the floor are rotten. Going on a metal run sometime to get 16ga and 1x2 square tubing. Thinking about diamond plate with rhino or lizard for the floor. What do you guys think??

 

[CrappiePoint]

“Someone” tacked in a piece of 16ga over a rusted floor. Double the work now.

Got the original floor removed and cut the rear cab support cut out and replaced with 1/8 2x4. Also got 4 new cab bushings built from some ford f350 ones. Next job is to frame the extension in with 1/8 3x3 and another 1/8 2x4 across the back.

Got the low range shifter mount removed from the u bracket and got it welded on with a new rear cab support. Welded on the 2- 3x3 by1/8 runners as well. Then spent 5 hours separating the new rear cab section from the donor.

Following this build closely. I am in the process of doing one myself but a few steps behind you but what the cab stripped down and ready to cut the back off. I am planning on moving the rear section of the cab back and fabbing in-between. Currently looking for a cross member to put in the back and leave the current rear in the middle.

I’ll get you some pics of removing the back section. There are some hidden tacks that slowed me down. Using the air hammer chisel was the trick for not damaging the donor.

I would appreciate it. I have already cut down the sides but still looking at the best way to do the bottom where I am not getting into the meat of it but have enough for the cab mount that will ultimately be in the center.

After looking at the cross beam, I’d cut it along the front of the rear cab mount (then after you got it on the table ) cut the floor material off of the front site of the bream at the tacks.

Hard to tell what you are pointing at in those pics with it off the truck hah. I was planning on cutting here across. Seems like that is what you are describing.

 

[CrappiePoint]

We are pointing in about the same spot. But I would cut it off at the rear of the e brake opening and then remove the tacks and floor on the table as to not damage the cross member. Just my opinion.
