Here's a link to the Tilton brake/clutch/master cylinder setup similar to mine. There are some good installation drawings that show how it would be mounted to a firewall. You need to make sure the firewall is strong enough, the pedals would be properly placed in the footwell and that there's room for the master cylinders and reservoirs in the engine compartment. I didn't notice any throttle assemblies on the Tilton site, but I'm sure other manufacturers sell something that would work.
