Doetsch Teck DT4231G replacement shock

[csbarracuda]

i need to replace one shock on my lowered 68 truck and i can't seem to find one to buy. I searched on the internet and found a part number close but am not sure if it is the same and Doetsch just changed the part number. The other three are brand new and I think they are the nitrogen ones. The shock is on the rear and is a Doetsch Teck DT4231G needed.

I bought the truck as a disassembled mess for $400 and put it together.
its hugger orange, lowered 4 - 3 with springs. the frame was sandblasted and painted eastwood black with all new SS brakelines, new frontend, brakes 12 bolt rear, cab supports and all the rubber mounts, decent bed. I am building a 400 sbc for it now, it currently has a mildly hot 305 attached to a rebuilt 350 with a shift kit. i'll put up a pic at a later time. PS i also have lots of parts for these as i have cut up and parted out a couple of them.
