Big block, early a transmission mount

The early A-body crossmember should work fine with a 727. Many folks have 727's in their early A's using the stock crossmemeber and mount (myself included). There's something else going on. Can you post a photo of the interference?

What's the 727 out of? Maybe there were some variations in 727 extension housings? Does it have an oddball mount or something cast in the top of it that's contacting the upper crossmember?

So an inch was a bit of an exaggeration, but it’s a hole off. There is a piece of rubber above that would allow it to line up but still closer than I thought it should be. No oddball stuff. Maybe the rubber mount is swelled up? Best I can do for pics right now
