Another 12v Swap question:

Hello all. I've got a '78 F250 Crew, 4x4, with 4.10s and it's a longbed conversion (person who "restored" it lengthened out the frame)

I've been doing quite a bit of reading lately on this. Have been keeping a powerpoint file on everything, tips, pics of mounts, crossmember mods, & other stuff.

I've got a couple questions that I've read a little on but not enough to satisfy my question:
1) I have a '93 3/4 ton 4x4, Auto. Besides the motor & trans I was planning on using the t-case & front & rear axles. With my frame, is it feasible to use the axles from the Dodge? Or is the spring-to-spring measurements all wrong? I obviously don't mind moving spring perches & shock mounts.

2) Fuel tanks. Let's say I'm only going to use the saddle tank. How do I go about hooking up the return fuel line? And is there going to be an issue with fuel starvation if I get down to a low level (say 1/4 tank)?

I think that's about it for now. I'm sure there will be more. The plan is to do most of the fabrication pieces of the swap during my 2 weeks off around Christmas. I'm hoping/planning for a 2 month downtime We'll see if I succeed.

Here's the rig I'm putting it in:

The front axles have a very similar center-to-center spring measurement. The only problem is, the Dodge axle is set up for 2 1/2" springs. The back end should be close but I don't know (tape measures are your friend).

Don't both of your t-cases have the same bolt pattern?

They may have the same bolt pattern, but I think the pattern is clocked the wrong way.

You have both trucks. You ought to go take a look-see and report back.

I ended up selling the '93 I had. Made some decent coin on it.

Also, now I'm thinking of going with a 2nd gen Dodge and use the motor/trans/t-case and keep my D44 until I can find a D60 and regear it.

When I get a 2nd gen, I'll use the rear axle out of it so I can have the correct ratio and drive it while I save up for a D60 for the front.
