Engine Bracket numbers?

yesterday when i was installing my mounts i used a redrilled 194 rear mount. and a 497 front mount unmodified. i found it on the dsm shelf at work and it happened to line up almost perfectly so i used it. where did 497 come from?

this is good to know. i think i have a few of these too. maybe an auto 1g? that's where i think found mine

Here's another thread where I asked about the front mounts. Not sure what yours came out of though.
