Gearbox Cross member modification.

The Rover 5 speed LT77 gearbox doesn't align with the MGB cross member, so it has to be modified.

This is the standard MGB cross member, some people make new brackets up and weld them on, but as I have the original SD1 bracket I decided to make use of it, the ends were cut off and a flat plate welded in place of the MGB brackets, which I cut off with an angle grinder. When the engine and gearbox were trial fitted, I marked the flat plate where the SD1 bracket sat, and the welded the whole lot together.

Home made de-rusting /electrolysis bath.
The crossmembers were very rusty and wire brushing them is difficult and messy, so we built an electrolysis unit in a wheelie bin, to de-rust them. steel rods in the corners, and then filled with water and washing soda crystals, then a current passed through it, and the rust falls away.

This is the finished gearbox cross member, de-rusted and painted with hammerite.
