This question may have already been asked, but there are too many reply's to read through check if it has. Are you going to make your frames availble for sale?
I was thinking of building something like you are building because I have sick of having too many classic cars and trucks, which I put a lot of time and money into, crashed and totaled because some parkinson diseased old fart, or ghetto scum crashed into it. I would like to build a truck so hard core tuff, that anybody that crashes into it is going to die, and my trucks frame will drive away without a scratch. Each one of these vehicles I owned on average for 10 to 20 years before somebody eventually crashed into it.
List of cars and trucks totaled:
1970 SS 396 Chevelle
1970 GS 455 Skylark
1977 C30 454 Chevy/Duallie
1982 K30 454 Chevy/Single
1985 K30 454 Chevy/Duallie
