Are you planning to market these? Put me on the list, I'm looking for tie downs now. Great product btw.
No I'm busy enough as it is. If you guys have a friend w/ a machine shop you should be able to make them. The "block" has a "pocket" that the loop fits into.
-fabricate & weld mounting plate (to suit trailer) to block
-drill 2 clearance holes thru block & plate to suit tiedown loop center to center distance.
-locate & drill 2 holes in panel tiedown will be mounted to
-slot panel between 2 holes
-mill pocket in block leaving 1/4" of steel between bottom of pocket & outside of block
-install loop in pocket & weld "stop plate" to the loop
-locate mounting holes in trailer & drill
-mount tiedowns to trailer
I can make a sketch of the block & loop to post if you want
