Stormy Posted October 13, 2018 Report Share Posted October 13, 2018 For Avanti 4042 Studebaker Int. offers Part # 1350251 the battery hold down bracket . This part is attached to the inside of the front left wheel well with 4 rivets of some sort. Studebaker Int. has been unable to find rivets for this use and the Studebaker Avanti Parts Manual shows the rivets, but there is no part number for them. Does anyone know what these rivets might be, and what tool is required to install them ? Thanks for your help. Daryl Link to comment Share on other sites More sharing options...
mfg Posted October 13, 2018 Report Share Posted October 13, 2018 (edited) I'd have to look at my '63 to know for sure, but no doubt those rivets are either 3/16 or 1/4 inch in diameter, with a depth of about 1/2 inch. These would be readily available at hardware stores, although you may end up purchasing a box of 25 or so. A pop-rivet tool is needed to set them....and inexpensive ones are available at many stores. (Harbor Freight, etc.) I'd use aluminum bodied rivets,...they don't rust, and are easier to 'pop' than the steel ones! PS...use a small, thin piece of sheetmetal or aluminum, on opposite side of fiberglass skirt, to 'reinforce' the repair!

Stormy Posted October 16, 2018 Author Report Share Posted October 16, 2018 mfg, thank you. If they have stainless steel rivets, that might be a good choice ? Link to comment Share on other sites More sharing options...

Your welcome!.....I wouldn't use stainless steel rivets for this job.....they're extra hard to set, and you're only anchoring into fiberglass. I'd go with an aluminum pop-rivet (body & mandrel).....they're plenty strong....stronger than that inner fender! Link to comment Share on other sites More sharing options...
mfg Posted October 17, 2018 Report Share Posted October 17, 2018 I checked out those battery bracket rivets on my '63 tonight.....they appear to be 3/16" in diameter. Link to comment Share on other sites More sharing options...

Stainless or std. steel pop rivets have too much grip strength for fiberglass use. Save those for metal/metal joining. All aluminum rivets with aluminum backing washers is the way to go.

Stormy Posted October 18, 2018 Author Report Share Posted October 18, 2018 Thanks for the ideas. I was worried about the ,[ is it galvanic action?] that takes place between aluminum and steel. Daryl Link to comment Share on other sites More sharing options...
Jolly-John Posted October 21, 2018 Report Share Posted October 21, 2018 (edited) I wouldn't worry about that, Daryl. Personally, I'd use something like a carriage bolt (no hex head, no slotted head) for a nice rounded appearance.This would resemble a rivet from the engine compartment side. Cut the bolt to length, if needed, although I've seen very short ones at the hardware store. You can also round the square shoulder under the carriage bolt head with a grinder or file, if needed. That's not a big deal...I've done that many times, when I wanted a rivet "look", but didn't want to (or couldn't) use a real rivet. To me, a pop rivet will always look....like a pop rivet from the top. While a pop rivet would certainly be functional, it would seem very unfactory-like in appearance. Just one other quick thought, in case you were wondering: I haven't looked at my all-original '63, but I believe the rivet (or whatever) and the threaded holddown bracket are painted body color. Someone will correct me on this, if needed. John Edited October 21, 2018 by Jolly-John Link to comment Share on other sites More sharing options...
mfg Posted October 21, 2018 Report Share Posted October 21, 2018 Auveco brand pop-rivets, in 3/16" and 1/4" diameter sizes, have a rounded 'head' which duplicates the snap-rivets Studebaker used when building the Avanti bodies almost exactly. I agree that some of the other brands, especially in the smaller (1/16"-1/8") sizes, have a 'flat' head look which is obviously not original. Once again, installed correctly rivets work very well, and without a washer and nut hanging off the bottom of them! Link to comment Share on other sites More sharing options...
Jolly-John Posted October 26, 2018 Report Share Posted October 26, 2018 Good to know about the large diameter Auveco pop-rivets having the right look. I have never come upon them in the past, although I do buy from an Auveco jobber every once In awhile.. Thanks, mfg. John Link to comment Share on other sites More sharing options...
