I was able to buy them locally, but that was bake in 1985. I was also able to find a "modern" car that had the same form factor for its shocks. I just remembered where the numbers where. The cars with the same form factor for the shocks are a lot heavier then a TR3, but for those interested the following cars have the same shape and size front shocks as a TR3:
80-81 Plymoth Grand Fury
75-76 Plymoth Fury
77-78 Dodge Monaco
73-74 Belveder and Satelite
For what it is worth. I would go for the real thing from Moss or TRF or VB or the like.
