55 3100 chassis swap

[Guyz55]

I am looking to swap out the chassis on my 55 3100 2nd series TF pick up . I am looking for what would be the best chassis to swap too ( C10,Tahoe etc) ...I would want to use a late model chassis of course . I was going to buy an IFS kit and power steering for 2500$ not installed .....until my gear head nephew came up with this idea which sounds like the way to go ......If I can find the right frame for my 55 im sure it will be under a grand to buy and I can update the brakes and FE components on it as necessary ....and by upgrading the chassis , I get disc brakes in the rear ...seems like a no brainer , just a lot of work .

Any and all input is welcome ...
