30 - 31 Coupe Spare Tire Support Bracket
 

Brattons part #1970 states for 30/31. What was used for 29.

Just the vertical brace in the middle behind the outer panel.

I assume dmacweb is referring to a rumble seat 28/29 coupe. Steve, are you positive the 28/29 coupes or roadsters didn't use the part shown in the first post? I have a 28 roadster that is going to have a rumble seat and a rear mounted spare. I need to know for sure whether the part is or isn't used on the curved inner panel.

Thanks Steve.
It turns out my 30 coupe has all 29 rumble parts.

I removed this bracket from a '29 Coupe rumble seat car...

Re: 30 - 31 Coupe Spare Tire Support Bracket
 

Same thing.

The part in question in post one is also used for 1928 Roadster with rumble seat.

The repro part is aluminum...the original was steel...get an original as it already has the the holes for the rivet atachment to the rear floor pan.

In my case, it's a '30 coupe but has '29 rumble parts. The curved inner panel does not have the hole for the brace bolt to the spare tire carrier. The radius curve of the repro aluminum brace does not fit tight to the curved panel. It's possible the inner curved panel is a repro and/or the curve of the repro brace differs from an original. I don't have an original brace to compare to the repro. If need be, I can get one but at the very least, that will require cutting a hole in the inner panel.

This all started when I just recently noticed the spare carrier did not seem solid to the body. When I checked, the bottom of the vertical bracket was not connected. I put in a couple of bolts and obviously it's much more solid now. That's when I noticed it did not have the curved brace. Before buying parts and doing mods, I'd like to know if the brace is really needed in my situation. Even with the bottom of vertical bracket loose, the spare has not fallen off since I've had the car. It's a driver and my inclination is to not add it.

Re: 30 - 31 Coupe Spare Tire Support Bracket
 

I have it from good sources that original curved inner panels have a "depressed" area near the upper part of the curved inner panel near the vertical bracket inside the panel below the lid. This changes the curve of the curved inner panel to fit the curved bracket and lineup with the hole in the vertical bracket inside the outer panel below the lid. This is to better align the curved stiffener/panel to the hole for the upper bolt that attaches the spare tire carrier. Repro panels don't have either the square hole cutout for the bolt spare tire bracket or the depressed area. It would require some work to add the depressed area and properly cut the square hole. I believe like several others here, ALL coupe and roadsters with rumble seats SHOULD have the curved bracket riveted to the panel to provide better support for the spare tire.

You are so right on that one Rusty! You couldn't of said it any better than that!

Re: 30 - 31 Coupe Spare Tire Support Bracket
 

I could be wrong but I seem to recall the stamped depression was added to compensate for the switch to the tall (9") rear panel. Mine has 7" panel.

Either way, everything is assembled and painted so taking panels apart is not a viable option.

Re: 30 - 31 Coupe Spare Tire Support Bracket
 

Could be mistaken, but I believe that the curved "banana" brace was used on all rumble seat equipped vehicles except for those produced in the first couple of months in 1928.

I doubt very much that you have the short version of the outside panel on a 30-31 coupe. The panel needs to be measured on the outside of the body, as it's impossible to measure the total height on the inside when the inner panel is in place. I think originals were about 9-1/2" measured on the ends and about 1/4" taller in the middle.

Re: 30 - 31 Coupe Spare Tire Support Bracket
 

All rumbles used the same part. The original curved inner panel would have a square hole for the bracket.

You should not need to buy the repro it is a fairly common part out in the wild. A good curved inner panel is a different story.

The repro curved panel is not right in many directions. You will have to adjust the position so the bracket mounts tight to the lower rear panel. If not then you will distort the panels when you bolt it together. I needed to beat a bulge into my repro panel to get it to the right position.

Are the originals forged steel?

I believe you are correct in that the shorter 28/29 coupe panels below the lid didn't need a depression in the curved inner panel to line up the banana bracket with the hole in the vertical bracket. However, Randy in ca wrote: a 30 coupe has the tall lower panel. I agree with him, 30 coupes definitely have the taller 9 1/2" panel.

Yes!

Is the inner curved panel only held in place by machine screws/nuts? The rumble lid is still on so it's hard to get pictures.

Re: 30 - 31 Coupe Spare Tire Support Bracket
 

My '30 coupe has a '29 lid. It also has the round tube rear bumper brace used thru '29.
