Default My Bronco cummins conversion (work in progress)

it is a 1978 Ford Bronco and it is getting a 92 rotary pump Cummins.

so my plan was originally to use the dodge overdrive auto and a Np 241 transfercase, but after getting some mock up pieces i found out that the combo, especially with the slip yolk on the transfer case, was way to long. so luckily i found an adaptor to use a ZF-5 transmission and then i could use my NP 205 transfer case.
so it came with a ceramic Southbend clutch and flywheel and the starter. it ended up being almost 16 inches shorter in overall length and it made the parts interchange much easier.

yeah it was on propane, it is turning out to be a real pain too, because when i put the tanks in i took out the fuel tank and all the straps and pick up, and i threw them all out.
didn't get as much done this weekend as i would have liked, cross member is in and bolted up, now i have to get my driveshafts done and exhaust done.

i was planning on buying a new tank anyway, but it is all the little bits and pieces that are a pain to find, luckily my brother just told me he is parting out his Bronco, so that is no longer a problem!

well got a few more things done in the last few days

figured out my hydaulic clutch, got the pedal and mount done and the master mounted and the firewall reinforced. just have to run the line and that will be done.

mounted the turbo (hx35) and the exhaust brake (BD) it is going to be a tight fit for the exhaust, my starter is on the same side.

hoping to get the exhaust done and the front clip back on and maybe even the rear driveshaft shortened and get started on the fuel system this weekend.

i will try and get some more pics up soon.
