I've got 2 7.62 cal Garands and would like to get a spare bolt body for each. How do I get them headspaced to the existing barrels? Is this something a gunsmith has to do? Does it involve going through a lot of bolt bodies to find ones that will headspace?

It depends if they are already fully chambered or if they are short chambered. If they are already fully chambered it is a matter of installing them on to a receiver, then checking the bolts for proper head space.
If they are short chambered, it is a matter of reaming the chamber to proper length. Not hard with the proper tools. The last one I did, I used a "Pull Through Reamer". It took about 2 minutes once the barrel was on, to headspace. Okay, well, maybe 5 minutes.

Since these are 'Spare-Bolts' I'm going to assume that you already have bolts headspaced to these rifles. What you're going to have to do is buy a few bolts. Look at the numbers on one of the bolts already in the rifles. See the -number? Like -12 or -17? or possibly even a 65 at the beginning of the bolt number. You haver to buy several bolts with the same - numbers and check headspace with each one.

Assuming you have the extra bolts like I did, I just took them and checked the head space with go/no-go gauges. The 3 rifles I checked all head-space just fine with the extra bolts.
Most will inter-change just fine but safety says check first. I have never heard of a percentage that would or would not.
A field gauge would work too and has a larger margin of headspace for passing than the no-go gauge.
