We had a Lokar firewall mounted transmission fluid dipstick from a long time ago, but since there’s nothing else mounted on the firewall I decided to mount it low.
Starting with two stainless dished washers, I hammered them flat and welded them together around the perimeter. This made them about the same thickness as the bracket I wanted to pillage and use for its 3/8″ hole.
This is the bracket I started out with.
I trimmed the slot off and merged the washers with the 90 degree bracket.
It sits pretty much in line with the engine dipstick now…
I finished the front spreader bar the same way as the rear to mount the license plate.
