Fast Lane sells the shims for $0.13 each, 5 sizes 1.15-1.85mm.

mccan:

You want a 12 point 27mm deep socket. Many places sell this size (try finding a 12 point 30mm deep socket - no go, go find a pro tool truck or order it online from tool stores like Ontool). As I recall Sears has this socket in the metric tool section. I have a Snap-On 12 pt. 27mm deep socket and I've used it to R&R my injectors several times without problems, as well as using it on the crankshaft bolt to turn the engine. There is nothing special about my Snap-On 27mm socket, so any other well made 12 point 27mm deep socket should work fine without damaging the return line nipples on the injectors.

Good Luck!
Tom
