Default fiberglass help

a friend of mine is getting fiberglass bumpers for his 77 celica. the question is how to mount them. the bumpers have no mounting points.

what would be the best way to mount it to the frame?
holes could be drilled and use bolts with the factory mounts. but he is worried about the bumper flexing and cracking at the bolt holes.
is there any glue or something else to fix the bumper to the mounting brackets?

thanks.

Basically I just need to know what to use to mount the brackets I make to the FG bumper

I think I would through-bolt it, because those fiberglass bumpers look pretty small and flexible, so they may break....



you could use the vertical black bumper pads off of the old bumper to hide the bolts, and keep it looking a little more stock, or you could run a strip of steel across the top of the front face and use bolts through there, similar to that stock one...

i would probably make a piece of plate steel with threaded holes as close as posible to the stock mount spacing. then glass in that plate to the backside of the bumper. just make sure you use short enough bolts that they dont go all the way through the plate, just long enough to get the whole thickness. then locktite them in.

i can't see pics here at work, but are the fiberglass bumpers actually just covers that go over the stock bumpers?

If so they usually glue on.

I used to see lots of bumper covers come into the body shop i worked at when the cow catcher thing was cool.

after looking at the pics, they look like covers to me.

See if they fit right over top of the crome bumpers

They do not just fit over the stock bumpers, they are much smaller and are a complete replacement

I figured I could through bolt them like many have suggested, but I am worried about it cracking with how much it will flex at speed.

another pic of the bumpers




and here is a pic of a different car with the bumpers, so you can see that they are in fact much different
