Bt7 differential

[Paul pugh]

The healey bt7 differential drain and refill screws require a square key to remove. Any idea where to find one.

Will a socket drive do it?

I just use a 3/8" socket wrench handle.?

It's 3/8. Fits, but loose. I bought a 7/16 bar stock and cut a short piece, but it needs to be filed down a bit to fit the fill screw. Just looking for the real thing, or what will work. That screw is in very tight.

Paul,

7/16" square stock, 8 point 7/16" socket!

Buy a cheap 3/8" -> 1/2" adapter and grind to fit.

Done. 7/16 bar stock works. Also buying replacement filler/drain screws from moss that use a hex key
