I'm building a 3/4 ton '48 using an S10 rearend and a Heidts Mustang 2 front end. I picked the M2 up for $1500 on EBAY including power rack, dropped spindles, sway bar, big block springs and stainless brake lines. If you shop around you can find some good deals.
I subframed my '52 Chev panel and that creates more work with the front fenders, bumper etc. That is why I'm going with the M2 this time.
Good luck with your build.
