Wheel Backspace Measurement Tool

Hello everyone. I am new to the this forum and I did a search but did not find what I was looking for.

I have a 67 Plymouth GTX that I just installed the Wilwood 140-9828-D 4 Piston kit. My 15" Mag 500's now require a 3/8" spacer (I hate spacers) to clear the calipers. The Calipers barely clear the tape wheel weights, too.

So in an effort to open up my tire options and guarantee clearance I am sadly moving up to a 17" VWW 45 wheel. I am trying to fit as much tire as I can at stock-ish height with absolutely no rubbing at any position in the wheel stroke. I am safely assuming a 245-45-17 will fit but the question is offset and back spacing.

Does anyone have a wheel measurement tool (http://www.thewheelfit.com/) in the SF Bay Area that I can borrow to get the right measurement? Or does anybody else have my setup that can vouch for the right fitment? I would like as much lip as possible.

Sorry for how long this is and thank you in advance.

I think you could accomplish this with a home made tool.....................

This site used with a measure tool should answer your questions. This site has been very accurate for me. Dave

Just need to find that measuring tool or a shop that has one.

Not that I can help find the tool but these wheels are a hellova lot cheaper than those VWW 45

They are much cheaper unless I want a custom offset and backspacing. Then the VWW wheels are a better value.
