Default Re: Rear Bumper Molding Question

I've been thinking about this and as having a little experience in plastics. If the main varianble in the part is in width (distance from the license plate opening to the corner) could'ne one use a donor piece and add length? It would be easy to add a section using quaility glues, scab a piece on the back, and then fill any inperfections with good plastic putty and paint. No one would ever know....

I'm going to try and find some cheap pieces from junkyard and experiment a little.

That might work, but like I said, I am pretty sure the Narrow body cars had the Rub strip molded into the bumper.

does anyone have a good picture of the trim itself? I wonder what it would take to make them.

The trim from the doors back are separate pieces.One positive here is the door trim are not ZR-1 specific.I know this,I used one from a base car.

I have also mentioned making it from aluminum on a CnC.
Make it solid on the back side and drill/tap holes for the hold down screws.

Same for plastic make it solid plastic and use lag screws like our tail lights from the back side.

Rhipsher don't you have access to a CnC?

I know all the pieces on a ZR-1 are separate.. is that true for 91-later narrow body cars?

You're incorrect, the doors on all ZR-1's are unique so we cant use any old C4 door...

He doesn't mean the door itself. I think he means you can use a door trim piece from a standard C4 and it will fit. ZR-1 door is wider, but is same length as a standard C4 door.

So the 91-95 ZR-1's have separate, removable trim pieces for the front, rear and side gills? On the '91-96 standard C4's, the trim on the front bumper, rear bumper & side gills is molded in and not removable separately from the main piece. Only the door trim piece and the small section in front of the rear wheel is removable.

.
On 91-95 the trim is molded in the front bumper and the fender panels.Doors,short QP piece and all rear bumper trim is separate from the bumper.If somebody has a piece of bumper trim from a base car I can take a look at it see what it would take to modify it for a ZR-1.I would never pay $700 for this part,I would make it out of WOOD before I would let somebody gouge the piss out of me for something that might have cost $100,tops.

Its plastic It can be repaired, the damn thing only needs to be repainted after the repair and you would never know.

I mean its ok to repair parts, cars ger hit once in a while it happens and with the limited parts available it might be a good idea to repair what you can when you can.

Yes. I agree!
I agree a lot can be done with damaged part, epoxy and sand paper.
Of course, if all fails, balsa wood...
