1950 Delta Rockwell Unisaw Mobile Base Fail

Decided to try something different this time instead of the WEN mobile bases I've installed on a number of my tools. Since the Unisaw is nearly 450 lbs, I thought I'd take a note from the source and install a Delta Mobile Base made specifically for their Unisaw. After all, what could possibly go wrong? Famous last words.
Well, for starters even though his is a Delta made product and made specifically to fit the Delta Unisaw...it wasn't made to fit a Unisaw from the 1950's era. Over the years Delta has changed both the size of the cabinets as well as the size/dimensions of the bases. As well all know, profit is the primary motivator so things will of course shrink or be made smaller over time to save on material cost.
Turns out this mobile base (the only one Delta makes for the Unisaw) is sized for the dimension of the Unisaws built after 1980 or so I believe. I note the dimensions of the mobile base as well as the dimensions of my base, so anyone with a saw base of these dimensions can chime in.
Needless to say this path was one of failure!
