Directly bolt on? No. If you're good at cutting/chopping/fabricating and have access to a couple lifts and other equipment..... are proficient at welding, and full of determination...........yes. Was proven by Caminkid! One determined son of a gun! And an awesome car! Was fun to see it at the 60th show!
For that last couple years My dad and I have had a couple 69 El Camino's under tarps wondering what to do with them. You see, they're pretty much basket cases. Rusted out floors, quarters, etc and there both non-SS's. We've tried selling one, but she kept followed me home. About 2 years ago...
Yea, his is a 69 but the same amount of work will be required! Good luck!
