I guess your older model truck must use a different cross member than the next body style that I have?? My engine fit perfectly without modifying the cross member or the firewall. The only issue I ran into was having to slide the transmission backwards 2".
The DCS mounts have 2 sets of holes to mount to the engine block at different heights. I don't remember which body style they were swapping into, but I saw a build thread with some guys using the DCS mounts and they cleared the cross member but they had to pull the dash, cut the firewall, and build a little box in the firewall to fit #6 cylinder.
I think in your case the cross member would be the easiest to modify or rebuild.
Like you said, no need to stress about it now. Deal with each problem as you meet it. Half the fun in this type of build is solving the problems that come from stuffing an engine into a truck it wasn't made for lol.

Been dealing with other crap lately, so not much done. Got the rear dana 80 axle pulled. Took longer than it should've, both floor jacks were giving me problems, and because the truck was parked on pea gravel, on an incline, at an angle, the damn thing was doing its damndest to fall on me!



I've sort of got a plan on how to marry the 2wd nv4500 to my ford np205:

4x4 nv4500 trannies seem to cost $1800+ around here, so I think it's much cheaper to convert my 2wd to 4x4, using these two parts. Not to mention I know my tranny is good.

https://www.advanceadapters.com/prod...spline-output/
I think the cast iron tailshaft housing is technically stronger than the oem aluminum 4x4 tailshaft housing.
The mainshaft is fully splined and supposedly better than the oem one.
I planned on rebuilding the tranny anyway, so I was going to tear it apart anyway.

I can save a bit getting the housing and shaft from ebay. Just not sure if they will be of similar quality.

Then, to get my np205 to marry it, I just need this expensive kit:
https://www.advanceadapters.com/prod...to-ford-np205/
The only problem being that I have to clearance a notch into the mounting surface of the cast iron tailshaft housing above, to clear the shift forks from the np205.

Then I'll get driveshaft lengths figured out.

I reckon this will be the most expensive part of this swap, other than the donor truck.

I really want to keep a married transfer case for simplicity and strength. I'm hoping to be able to use the stock ford transfer case side mount, and just reposition it wherever the t-case ends up.

Going to a divorced setup would require a different version of the np205, which would be likely just as expensive. And I know mine works.
Getting a dodge version would have the front axle yoke on the wrong side of the truck.
And I really want to stick with a 205 as opposed to the nv241 that came in these dodges, not to mention, I only bought a 2wd dodge.

So, what do you all think of my plan? Any problems you foresee? Gotta pay to play, any way I figure it.

I've started tearing into the front dana 60 axle. If interested, you can read about it here:

https://www.ford-trucks.com/forums/1...-and-swap.html

Once I'm done fixing it up, I'll tear into the cummins and swap work.

I'm about done with the axle, and will be tearing into the 12v soon.

While the engine is out, I'd like to replace every gasket and seal I can get to, with the exception of the head gasket.

Can you guys recommend some reputable vendors to order gaskets from? Specific kits I should go with?

I tried searching on the forum, but only found a lot of arguing, and out of date or out of stock links.

Thanks.
