the chassis between the 3rd and 4th gens are identical up to the front of the floor pans, the front subframes and front clip are completely different. as far as strength goes the two are probably pretty similar comparing hardtop to hardtop, i can see the 3rd gen t top cars being weaker than a 4th gen t top car due to there being less roof.
my car was pretty tight back when i drove it, with a stockish 305 under the hood i dont think it had the chance to be twisted. i put the alston SFCs in a while ago, theyre the tubular ones u see in that pic that connect the actual subframes together. the bmrs go from the lca mount down the pinch welds and across to the subframe. running both types of SFCs triangulates the chassis on both sides and is the strongest chassis you are going to get without a cage or serious chassis work.
