D4 7U footprint

I hope to have pics in a week or so. Been without Cat for 5 years, sold my 6U SP....big mistake. Looks like I've bought a 7U with TB dozer blade. Here's my question, I believe outside track width is 60" but what is the inside as i don't know the standard pad width on a 7U. I have access to a Belshe tripple axle Backhoe trailer and am wondering if the tracks will fit in the channel floor or do I need to bring wooden cribbing.

Hi Clint,
welcome back to the Cat family.
The standard grouser plate is 13" according to my sales sheets.
Cheers,
Eddie B.

60 inch is the gauge, centerline of sprocket to centerline of sprocket. Dozer pads are normally 16 inch standard but can be wider.
