Stop in for a cup of coffee

Lots of free plans on line. They make for a good base plan.
Can't find my old drawings. Red wing something had free on line drawings. .
I would just beef them up a bit for your car. Around $300.00 and a days work should get you there.

I used the Redwing plans and built mine. Good stuff. When finished, you could easily sell it for more than it cost to build it.
