Not to much extra in the rear maybe an extra leaf or two but as far as putting in a 4bt the you will have a lot of extra weight up front plus with torque etc. You may need to strengthen frame and really beef up the suspension considerably.

i have heard that i will need to shorten the passanger side of the axle. i am going to the junk yard this weekend to pull an axle out of a donor (hopefully) for the time being am going to just do the shorten and after i get the engine swap complete ill be putting stronger leaf springs if i need them?????

Mainly stock 4bt you can throw in a ford 8.8 with a super 88 kit on the axle and it will be the same length as the d35 and be just about as strong (with the super 88 kit) a d 60 plus.

The front axle id say a d44 with some good shafts should be fine I'm assuming your running 35-37s, but I also don't know what gearing and I don't know the specs of the 4bt. You definitely won't break a good d 60 though

i am thinking more torward the 60's because they have proven to be bulletproof. i am probably not going any bigger than 37s for tires i was looking into the 44 but im not sure where i could find one the junkyards around here are retarded when it comes to this stuff and are no help. what years and makes could i find a 44 front. im looking to run 3.73 gears, i think....

44's will be fine for 37's. And if you EVER by some MIRACLE chance break something, you can upgrade them to handle what you need them for.

I'm not sure where to find a 44 front though.

14b over a 60 every day for me. if you are running ton's then nothing smaller then 37's or else your new hobby might as well be farming due to the fact that those diffs will be plowing into everything with smaller tires.
