Since there couldn't be much to it, taking that measurement. I would think, that they wouldn't mind measuring that for you. Since you've had them do some other work on this same engine. I'd suggest that you take it with you, and visit the shop. Talk to the guy that you talked to before, about the casting defect/crack. And ask how you'd go about measuring for that shim. Tell him what you don't understand about the procedure. Or that you don't have the tool, whatever. Maybe offer him ten bucks. My guess would be that you'd just use a feeler gauge. Making sure that the crank is pulled forward, if it has any play, front to rear. But I've never dealt with that, and without seeing it in person, I can only guess.
