Im planning on the TCI front end. 2" drop, power disc brake, rack and pinion, shock tower delete ( relocates to outside of the engine compartment which means a big engine in the future ) & additional frame support. The main reason I've decided on this is because the shock tower on the passenger side has cracked, the lower control arm was bent backwards affecting the other components. The car also came with manual drum brakes and manual steering. Total cost for all that to be replaced and upgraded to power steering and brakes is about the same price. Going to have to spend it anyway and it makes more sense to spend on a modern upgraded suspension than just replacing the 40 year old setup with the same.
Cost is not really a big issue, time on the other hand.....
