Keith,
I wouldn't do it. The pin ons are made MUCH lighter with less structural integrity. They even recommend pinning the bolt ons as a safety factor. I've been doing some research lately.

BTW,
If the pin on fits an 81 Monte, I might be interested.

the only way to even try to make a pin on hood into a bolt on unit would be to seperate the inner and outer panels , and then install large steel reinforcment plates before bonding everything back together

the only way around sererating the 2 panels would be to cut access holes in the outside and slide the plates in, but this causes an obvious repair problem

i wouldnt advise doing it either way

I don't know if this will work for you, you have to see if you have the room in your inner panel. (skip to the last section if you have no inner panel) I have cut holes in the back of the hood inner panel, then shoved a 3/4" square steel tubing about 3'-4' long, (or as long as you can work with) with a 1/4 X 1X 12" plate welded on it for the hinge to bolt on to. I cut away some of the tube to keep the height at 3/4" with the plate welded on. Once the hole is cut, the piece is test fitted until you can get it all the way in. Make sure the steel does not change the shape of the hood. Drill a hole in the inner panel at the front end of the steel so you can put a sheetmetal screw into the steel and pull it up tight to the inner panel. Put a bead of epoxy, panel adhesive, (steel/composite compatable), on the part of the steel that will come in contact with the inner panel. put it in place then screw it tite to the inner panel. when the epoxy cures, drill and tap the hood hinge mounting holes. Don't let the epoxy or the steel come in contact with the underside of the outer panel unless you can stand some transfer of the glue bondline pattern. you can patch up the hole at the back if you want, usually it doesn't show. I did this on a hood a few years back for a customer, but I can't remember what kind of car it was. I remember that the inner panel had alot of room in it. That made it easy.

Does this hood have any kind of inner panel? I guess I should have asked that first. Doh! Let us know if it has no inner panel . I can help with that too. hope this helps, Mikey
