Early a K frame mod questions

Have any of you purchased the Firm feel K-frame reinforcement kit for the early A-body K-frame? If so, what all comes with it and do you have pictures? The firm feel web page doesn't show much and it looks as though you need to call them with questions and to place an order.

Next question. Have any of you modified your early A-Body K-frame to accept the later K-frame spool type engine mounts and the later design double mount idler arm bracket?

I have a spool mount V-8 K-member that I'm thinking about cutting the mounts off of. I haven't taken measurements as of yet and I haven't looked into the dimensions or the geometry of the idler arm yet. I also have no idea if the spool mounts will interfere with installing my 340, clutch linkage, and or Dougs headers.

Any thoughts or insight would be greatly appreciated.

Thanks
Jason
