am I going in the wrong direction?

Schumacker sells everything you need from the engine mounts to the headers to the torque strapped to the transmission mount

but you're also the only to have to check the car out. You're going to probably need to do a rear end 8 3/4 rear, torsion bars, brakes, high pressure fuel lines, drive shaft and God knows what else
I have a budget of about 18k to do the conversion and about 6 k for paint and body I am dropping the hammer on this build at least for me this is big dollars.
