Sorry the part was at work when u wrote this. Part number A227. It's a 3/8" drive and it's as deep as a shallow 1/2" drive socket. But is a really hour socket on the inside. It's a gamble I guess if it's going to work. I normally use a 27mm deep 1/2" drive but I've been worried I would ruin into a situation where that was to much for the right motor compartments.
As I said though if it doesn't work I'll find a use for it.
