Craig:
Thanks for the compliment and the question.
Dwaine is going for a more authentic method of attachment. You can follow his lead and silicone some flat-head machine screws in place or you can use a two-part epoxy on the screws/bolts (which might be a little bit stronger).
The Spears themselves were specifically designed without the original studs so anyone could add them to an A-38 (or any other pump for that matter). That way, if you had a pump that did not come with the Spears - or you had filled the holes when you re-did your pump - you could still add them.
Personally, I would use a strip of double-stick FOAM tape. The kind you would use to attach body-side molding to a car. Not the kind you would use to attach a photo to a piece of paper.
Cut a piece of tape from the roll about 3" longer than the Spear is tall. Carefully cut the foam portion (not the backing strip) about 3.5" from one edge and remove this portion of the foam. Attach the foam tape firmly down the center (on the back) of the Spear(s) and set them aside.
Moving to the pump doors, use a Stabilo to mark the centerline of the door and draw a line up from the bottom a bit taller than the Spear. Position the Spear centered left-to-right on the centerline and almost flush with the bottom of the door. Make sure to have the 'extra' backing tape folded over at a 90-degree angle (so it points to the left or the right - folded 'away' from you).
While holding the Spear fairly firmly so it does not change position, slowly pull the backing tape off the remainder of the foam. As you remove the backing tape, press on the center of the Spear to set the adhesive. When the backing tape is fully released, go back over the Spear and firmly press the center to fully adhere the foam's adhesive.
That's it.
If, for whatever reason, you need to remove the Spear(s) at a later date. Simply pull a thin piece of 'mechanics' wire through the foam and the Spear will release. Then all you have to do is 'roll' the remaining foam off of the door and clean up any residual adhesive with a little 'Prep-Sol'.
This is the method that I use for any type of trim that attaches with the foam tape. It works, and it's not tricky to do.
Hope this helps.
Later . . .
Jim
