Will,
I have a spare pair of fiberglass Euro GT5 bumpers (as on my GT5, photo below). They are larger than early style bumperettes, more like a two piece 74 bumper that mounts directly to the body. I think they will suit the front style you have which are also same as my GT5.
I'll pull them off the shelf and take a photo to post as I think they need some mounting bolts fiberglassed in.
