Stud checking tool

A small squaring tool for checking the studs that support the bell housing in a Toyobaru twin. Needed because I bought an engine and the studs arrived bent. This enabled me to put new studs in and check that the upper oil pan that the studs are mounted in was not damaged. It was not, indeed, damaged! 

Simply print the file, place on the top of the stud, and then use a square to check it. This is large enough to clear the nut or a bolt head if that is all you have laying around to check with.
