350 b track frame wear plates dimensions anyone?

[mc_mike]

Working at rebuilding the undercarriage on a 350b crawler loader. I need new wear strips on both the track frames for the front idler and wear strips on the front idler itself. Anybody got dimensions for these parts? I just need to know length width and thickness of each, I can figure out the hole pattern in the ones with holes. Should be part # AT18850 & T20851

Thanks for any and all replies.
