2x2 tubing is too big. you would needa 1 1/2"x3" tubing to not be seen. ive got 2x2 under my car now for the rottisserie, sandwiched to the floorpans and you can see 1/2" of the tub. would be better with thinner but wider tube. i'll be designing a set of connectors that are not necessary to penetrate the floor. when i do, i'll post measurements and instruction on building them that anyone of the members here will be able to understand! even be able to weld them YOURSELF!
Have you had a chance to come up with a working design?
Still looking out for the best value.
