1950 Chevy panel with IFS project

[Michael_e]

As title states, I want to convert my straight axle 1950 Chevy panel truck to an IFS system. Here are some of the requirements I'm after. Side note-I'm looking at a LQ4/4l60e drive train, but that will be in a different thread.

I want my panel truck to be my daily driver and shop truck. I want to be able to cruse down the highway at 75 or so and track straight and true and a ride that is somewhat close to that of my 1997 GMC 1/2 ton. Also, I want to be able to tow either of my trailers ( 16ft double axle flat bed and 22ft double axle enclosed trailer) with say a max load of 4k lbs. I don't plan on towing everyday. I'm guessing maybe 6-7 times a year.

So, here's the question...is there any MMII style ifs kits on the market rated higher than 1/2 ton? Are there any MMII style kits for 6 lug hubs/wheels?
Would I be ok with a 1/2 ton kit and using 11-12" rotors and matching calipers?

If there's something I'm forgetting, please advise.
