Beck, who used to work for Off Road Design, makes a bolt on tube chassis for a k5 frame. He had one at Moab this year on a trailer on display. Very nice setup. Problem is, now that he doesn't work for ORD anymore I have no idea how to put you in contact with him...
Ditto on Beck. His name is Beck Herring, he had a "Beater Engineering" sticker on the chassis and his buggy. No advice from me other than to call directory assistance for Glenwood Springs, CO. and see if they have a listing.
Well after searching through everyone's moab pics for 45 minutes I found this!
As Ryan said, his stickers said "Beater Engineering" on them but he told me he didn't have a website or anything... I didn't get one of his business cards. If your interested in it I can probably find a way to get ahold of him.
I believe that the Hendrix chassis would work for your application. The fit of the Hendrix chassis onto the Toyota frame is up to the end user. I placed mine a little higher than some of the other builders in order to have enough head room. There should be no reason that you couldn't fit a Formula Toyota chassis onto a Blazer frame if you place and fit the tubes correctly between the Chevy and the Hendrix. It is certainly an inexpensive way to get the project started.
It might depend on your location. If you can pick up the chassis in Santa Margarita as I did, then you don't have to pay a shipper.
