First....Welcome to the forum!
We are currently working to put together kits, but already offer many components to help you do the swap. Here are a link to some of the parts, but glad to go over in detail. PM, email or call us.
I would look at the Dirty Dingo Double D mounts. They are very popular, and have the ability to move the engine forward if you want. We can get Hedman headers which have mid and long tube header specifically for the LS swaps in the C10's.
