1st gen Crew Cab plans

Been wanting to build one of these for years. Starting to do some more research on this again today and found this forum. Been reading through posts all afternoon and think I have a general plan. First let me say thanks for all the hard work and info out there.

I have been looking for a 92/93 Extended cab W250 with a cummings for awhile now that would be the base for a crew cab build. At this stage I'm looking for opinions on what would be the easiest build process.

Could a 92 or so ext cab long bed be used with an 85 crew cab and short bed? Or would the wheel openings in the bed be off? I'm guessing lengthening the frame is the only real way to go. Leave the option of using an 8' bed that way too.

From what I read an 85 crew cab body will bolt up with most everything except the firewall is different. What all would need to be done to a crew cab tub to make it bolt in usable assuming the frame work is done?

I'm hopping to end up with a 92/93 crew cab cummings in as close to OME looks as I can get.

best thing to do is find a crew cab truck and put the cummins in it.

'92 W350 cc/sb project, '89 W250, '91 W250, '90 D350,'92 D250... Its all junk!

Thats what I'm thinking. I'm betting there are morth then a few out there with cummings already too. Saw a 2 wheel 85 crew with a cummings for sale yesterday. What would it take to convert to 4X?

Check out this thread for 4x4 conversion: 84 Dodge Crew Cab 2wd to 91 Cummins 4wd.

Both the crew cab short bed and club cab long bed have 149" wheelbases, but you can't swap stock cabs directly because the crew frame has a longer lowered section under the cab. If you did something like draginmopar's post (married the cabs), you might be able to put a crew cab on the club cab frame (with cab mounts moved), but rear seat would not have the leg and/or head room of a stock crewcab. You would also need to cut 4" off the back of the frame (longbeds have 42.25" rear overhang, while the shortbeds and Ramcharger have 38.25" overhang).
