Johnson Reveler Electronic Engine Tilt

[reveler captain]

Hey everyone! I just picked up a 1967 Johnsons Reveler and fixed up the engineto go on the lakes. It has an old fashion rack and pinion electronic engine tilt. When I was testing it in the water I trimmed down the engine and it slammed into the boat knocking out the retainer cap for the worm gear and it sank to the bottom of the lake. Does anyone know where I could find this part? If not does anyone have the dimensions so I could get one made?

Thanks
