Howdy Chris, first off incredible work on all these rigs and I am very impressed and interested in your kit. I am definitely a few years out on a build, but your products have got the wheels turning. I have done leaf spring solid axle swaps on my 1997 Dodge 2500 Cummins and on my 1996 Toyota Tacoma both using 1979 Ford Dana 60's and without a kit. I like the idea of purchasing something that I know will work instead of all the headaches and hassle of figuring it out myself. Caster, steering, etc all were issues that I encountered and since resolved. I had a 1997 F250 with the 7.3 Powerstroke before my Cummins that I liked, so my ideal van would be a E250-350 7.3 Diesel probably with the extended body. I realize your kits are designed for the 99-2003ish Dana 50's and 60's but wonder if you have ever used or considered the late 80's to early 90's Kingpin Dana 60's in the F350's. I did some research and it looks like the 99 style Dana 60 has spring perch centers at 38" and the KP 60 is 36.5" I don't know if there is a possibility the KP 60 could be adapted to your kit? Personally I am a big fan of kingpin knuckles over ball joints and there is no need for a free spin kit with the older style KP 60. I am not worried about losing ABS and would probably swap in a Sterling axle or even a 14 bolt out back. My other question involves the possible use of a divorced t-case such as a NP 205. I assume the issue becomes length and interference with the fuel tank? I apologize if these answers have been addressed elsewhere and once again I love your work
Thanks
Jake
