Duster small block to big block engine mounts

Who makes engine mounts other than Schumacher. Need to go from a small block to big block, they're out of stock currently and I didn't like the way I was treated at customer service. Was looking to spend my money else where.

I had a duster with a spool mount k. I was able to modify a factory mount, not the k, to get the BB bolted in straight. I cut and moved the spool and welded it and kept spraying it with water to keep the rubber from melting out. Worked great with a chain on drivers side, went 8.90s at 150
