360 motor mounts (spool type)

I’m about to do a slant to 360 swap. I have the V8 K member. I’m looking around for motor mounts. I think the 318 Mounts with washers is how I’ll have to go. I’m shopping on Mancini’s site etc. all I seem to find are Poly Mounts. My experience with Poly is squeaky and crack over a few years. Who still makes a rubber factory style mount that’s worth a darn? Thanks.
