They are basically the same as the last years of type 3. I know all of the type 4's had' the impact strip, I can't remember if the type 3 did on everything. Actually, I beleive the structure inside of the type 4 chrome front bumper was slightly different. Also, the ends wrap a few more inches around the sides on the type 4, so the impact strip would be longer. But the front curve and the mounting spacing are so close on the type3, that most people do not notice. But the fronts are different. The rears are the same. Ray
It's just as hard to find good Type 3 bumpers. Guy in the local vdub club just spent mega $$$ to send his originals off his 69 type 3 fasty (the one on my web page) out to Texass to get them triple plated.
