thunderbolt clone suspension
check out the suspension used for a fairlane thunderbolt. they moved the spring towers out. BUT THEY were POOR handling. the early falcons had a lot of bump steer, especially when more horsepower caused more front end lift. especially when you took your foot of the gas and the front end came down faster than it rose, when you accelerated you turned the steering wheel to correct . How solid is the front understructure. any internal corrosion ?How strong is the cowl -air intake structure for the heater. that was part of the load path for the front suspension. .the heavy gage spring pocket spread the loads over a larger area of the "boxed frame" part of the front structure. I would question welding the upper coil over mounts with out additional front to back support. the stock lower strut arms and ball joints were not designed for the loads that would be imposed by mounting the springs..I would seriously consider building a new front frame with rails extending to the rear suspension pickup up points, good bracing, roll cage, then use a MII design suspension. and hang the front sheet metal... when you start modifying a unibody car there are a lot of things you might not think about. retired Ford engineer.
