Rolling on a budget

Probably about the cheapest and minimum way would be Schumacher mounts and Scarebird front disc brake conversion, then just add some bigger torsion bars and you should be ok on that front.

However, unless it's already been done, your front suspension really should be rebuilt. So then you could do the above and just rebuild the front suspension, OR better yet, get a '73-up K-member with the spool mounts and the entire front disc setup. Rebuild all that, bolt on the 360, and slip out your old K/engine and slip the new one in done. If at all possible, this is the route I'd go. Just find a good donor car to get all that from and you're good to go.
