Homemade wheel backspace measuring tool

good link. just need to be sure that the flat bar is made for your overall tire height. they didnt mention that in the article. to check different tire heights, you can make an oval hole on the flat bar, and slide the threaded rod up/down as needed.

I was thinking the same thing, that bar needs to be adjustable.
