replacement mounts for Hyde A mount

[Ed Alt]

I've got a Hyde A type that did it's time with a Webra 1.60 and now is needed to hold an OS 1.60. It appears that I could make it fit by slicing off the webbing on the top of each beam and maybe just a little light sanding inside the beams to make a snug fit. However, it might be cleaner to start over with replacement beams.  Someone told me these are basically Sig beam mounts that Merle uses?  Checking the Sig website, there doesn't seem to be an exact match, but P/N SIGEM003, meant for .61 to .90's looks like it could do the job.

Is this the right part to get?  Also, what's inside these mounts for those beam mounting bolts to grab into? 

Thanks
Ed
