Re: anybody built theier own CJ frame?
Actually I don't have to be a metallurgist, and I know my welding
ability: http://www.----------.com/aircompressor.jpg I let others make
my chassises, Like Dragmaster Chassis made this sling shot I drove to a
hundred and eighty miles an hour: http://www.----------.com/dragster.jpg

Re: anybody built theier own CJ frame?
Yes, most of my wheeling is now from County line Road, Ocotillo
Wells, CA with my Son: http://members.aol.com/Larr------/index.html And
Son-in-law: http://home.att.net/~taschers/index.html It's sixties miles
closer, and we can get further away from the crazies:
http://www.atving.com/atvconnection/...ksgiving00.cfm
Your friend sell his '72 Wagoneer, yet?
http://home.goldrush.com/obsoelyt/IMG_2771.jpg I need another project
like another hole in the head. Maybe, I shouldn't tell you, but the
bleeding heart liberal SMOG wackos pay the junkman a thousand bucks to
give the owner of a V8 to break it, at least down here.
