I have no clue on how strong that stub shaft is. I asked them the same thing and they said they havent had any issues. It is pretty thick. And im hard on the pedal all the time cause I like to move. And I have 40 inch Ground hawgs. I havent had an problems.

That's what I wanted to hear. How much do you know about the 518 transmission?

Not really anything. I think its like the 727 but with overdrive,and obviously longer. Since I have the bronco thats alot shorter than a pick up ,I was limited on space. So I had to go with the shortest automatic non computer controlled trans I could. I would love to have overdrive,but It aint going to happen. My next step is to take out my 4.56s and either go to 3.73s or to the stock 3.54s. I dont want to lose a lot of power turning my 40s but I need so highway driving back. Just look up the a518 and read up on it. Thats what I did when looking into this whole conversion. It taught me alot about these trans'. And transmissions are a weak area of mine..I can say these 727s are the simplest trans to take apart and reassemble. I think the 518 is similar.

Yeah basically are the sane transmission just the tail end of mine has the overdrive. I have been trying to read up on them just can't seem to find exactly what I'm looking for. Also did u make your motor mounts or buy them

For the engine mounts,I copied fordcummins design. They wanted $225 for them. Are you F ing kidding me? All it is, is a piece of steel bolted to the block,U channel welded to the steel,and a gusset underneath going to the 2. It took me a couple of hours with my plasma cutter and welder and I was done. And the steel was probably about $40 If I had to guess. We have steel at work So my boss let me take what I wanted. As for the radiator. Its up to you. I wanted to keep things simple and easily replaceable. I figured anything that I could use that was the broncos I did. That way I just go in and say I need whatever part for a 78 bronco. And with the engine and all,A 91 dodge w350 with a diesel. The less mitched matched parts the better. That and the availability of the stock parts.

I was thinking the same thing I don't have a plasma cutter but I can sure make them in a few hours. How did you know how long to make your mounts and where did you find the rubber bushings for them. And I think they are even motmre to buy now from ford fu@kums

I cant remember the length. Ill have to measure them. I had too much and ended up cutting them down,which was fine..As for the rubber,since I didnt know what ford cummins was using. I bought stock dodge motor mounts. I figured out where to drill the hole in my frame and motor mount bracket and bolted them in. A little pain in the *** but It worked.

If I could of found out what they were using Id do the same. IF you happen to talk to them and find out what they are let me know. I thought at first they were the rubber from the radius arm bushings for my front suspension. So I bought a bushing kit.. They werent..So now I have an extra kit for when my bushings do go. Eventually Im going to make a thread in this section of what I did,but have to get more pictures loaded into the computer for the thread. And pre write it up so its good. And thats what I did was go long,and when they were hitting my coil towers I realized I had to narrow them down,haha
