tranny different or not
is the 4 spd tranny in an 85 f250 2wd different than a 4x4 tranny. what kind of front suspension is in an 85 4x4. are the oil pans different in 4x4 model 6.9's. i am wanting a 4x4 of some sort and trying to trade my 85 f250 for one but no luck. nobody wants these trucks.
or swap to 4x4 on this but i think that is going to be too much

250 and 350 4x4 trucks had leaf springs under the front.
Oil pan is the same in both, the cross member dictates that.
I have located a 1986 F350 crew cab two wheel drive dually truck in perfect shape close to me.
It started life as a 460 C 6.
The price the owner wants is great for an 80,000 mile complete truck minus the engine and tranny.
He knows how I like the 86 body style and how I have been wanting a crew cab so he offered it to me.
I just don't think I want to get into all the headaches of the swap to manual diesel and 4x4.
Still thinking though.
Looks like all the holes to bolt the leaf spring hangers are already there in the frame.

It shouldn't be all that bad considering you already have annother ford of the same era to use as a guide when fitting things in. Personally, I think putting in leaf springs in would be easier than coil springs. The only thing stopping be from going to 4wd are my 3.08 gears, I already have the transfer case. Unfortunately, front differentials only go as far as 3.54 in the fords, so I'm stuck for now.
Remember how hard it can be to get a 4wd ford of this era in good shape.

i know somebody that has a sister which owns a junker 87-92 f250 4x4 which is trash. if he can get in touch with them, i am wanting to get the whole truck. but i think those are IFS suspension. it is also an auto tranny i believe and mine is a manual so if the transfer case is connected to the transmission, i may still have a problem with that part.

The 4x4 IFS suspension is still leaf springs.
A monobeam like a Dana 60 will bolt right up to the same springs.
With air tools and a helper, swapping from IFS to monobeam is an afternoon job.
Knock the tie rod loose from the steering sector, remove the calipers from the brake rotors, remove 4 U bolts that hold the axle to the springs, drop the driveshaft, and I can't remember 4 or 6 bolts out of the cross member.
The IFS is out.
4 bolts in the trac bar bracket, 4 U bolts over the springs, calipers back on the 60, hook up trac bar, attrach steering linkage and reinstall the drive shaft.

i recently conversted a crew cab 2 wheel drive to 4x4. i made the brackets for the swap. i used a highboy axle. they are expensive but my buddy has a junkyard full of 73-79 fords. it took some time but only costs were the axle and 3/8 steel plating.

i can get you some pics. the truck was an auto when i started but swapped to a ZF 5 speed. as far as the t-case i took the tailshaft off the tranny and hook the t-case on. the rear driveshaft was originally a 2 piece with the carrier bearing. i removed that and got a one piece shaft made and not using the carrier. the t-case that i used was a BW 1356. it and tranny came out of '94 f-350 with 7.3 turbo.
