Bumper gaurd mounting holes

[misty70]

Are there any templates out there that show the placement of the gaurds and holes

[willie]

Walter i would bet the manual will have it in there somewhere!!   Maybe someone else will jump in.  Or i can check tomm for you!!!

I seen a gm ( over the counter) kit for sale on marketplace a while ago, NOS in box and he had a picture of the template. So someone has to have one. Sorry I do not.

If anyone ultimately secures a template, add me to the list for a copy as my ‘70 will be wearing them once again when it’s makeover time.

I am interested

This may help a little

I did a quick google search on the GM part number off that sheet (3974022), It led me to a post from our very own Dennis B (McFan) that may be helpful.

If you already have a set of front and/or rear guards, it is super easy to make hole drilling templates.  Just get a clean, stiff piece of cardboard roughly 9" x 12" and a fine-point marker.  Lay a rear guard on one side and a front guard on the other, carefully trace the curvature of the bumper contact edge and mark the exact location of the threaded hole(s).  See photos below.  BTW I have pretty extensive photos of each step of the installation process for both front and rear guards if you need/want any.  Just PM me.  Be sure to use a level or framing square to be sure you mark and drill the holes perfectly vertical (perpendicular to the bumper) or your guards will alway look wonky. Good luck!

My bumpers are not on the car was trying to do before installing them

[MCfan]

I see.  Well, the front bumper shouldn't be a problem if you can lay it upside down on the edge of a long, level table. The bottom edge hole should already be in your bumper so use it to "locate" each guard with a loosely inserted bolt and let gravity position the guard vertically while you mark it's location outline on the bumper.  Then use your template to mark the required upper hole exactly in the middle (horizontally) of the outline.  I suggest very carefully center punching and drilling that hole, remembering to apply some paint or permanent sealant around the exposed edge of the hole to prevent future rusting.

I would think the rear bumper could also be done on a long, level table if properly supported.  Maybe you could even do it with the bumper in its natural upright orientation.  In any case, a level or square could be used to ensure proper vertical alignment.  I wouldn't hesitate to try installing guards on either or both bumpers when they are not on the car.  Good luck.

Edit: (I see the photos came out in reverse order again - not sure why.)

Happens to me occasionally too, no matter what I try. I usually go back and 'Edit' the post by 'cutting' the picture in question, then 'pasting' it in the position I want it to be. It's a good idea to add a few 'spaces' between pictures first. Makes it easier to paste the pics where you want to place them. Note: this is done in the body of the post, not at the very bottom where the attachments are located.

Great information you have provided too, Dennis. Thank you for taking the time to post this type of stuff. You're always very thorough.
