Splash shield brackets, accelerator pedal bracket

[Ronald L.]

Is there a difference in the 64 - 67 accelerator pedal/ splash shield attaching brackets?

These are the 1966 part numbers:
RH 3846938
LH 3846937

How about the right hand side brackets?

Are the repro parts correct with the weld nuts?

The RH side original versus a reproduction part are shown in the picture - no way close - about 1/8 short in height and the radius of the bends is not close to the original part.

Anyone seen this before?

Ron,

the repros have been like that for over 20 years. Also the weld nuts tend to break off when you rivet the accelerater bracket in place. If you have to use the repro before you rivet it into place tighten it down with 2 bolts to hold the weld nuts in place. This sometime stops the nuts from falling off.
I usually try to use originals.

Hi Rich,

I have a ex rusty original RH bracket where I noted the difference, pictured above.

Was wondering if there was a change in those years between 64 ~67.

I'll take that as a no.

On the LH side, my mangled original seems closer to the repro in height between flats, but hard to tell for sure on the car and yes, that one lost the weld nuts many years ago. Are the weld nuts on the repro visually exact?

Re: Splash shield brackets, accelerator pedal bracket

Here's the passenger side (at least I assume, due to no evidence of those square nuts being tack-welded -- otherwise LH and RH are the same) the part #s are the same in the '65 AIM, and as Ron quotes in post #1..

I measure the "step" at exactly 1/2".

Re: Splash shield brackets, accelerator pedal bracket

My Mar64 still has original brackets;
Left 937 measures 0.37 has two welded square nuts
Rt 938 measures 0.56

(measuring from top to bottom so thickness of material is in twice)

Re: Splash shield brackets, accelerator pedal bracket

I measured the left side on car radius to radius at 3/8".
The repop same thing.


On the right side - 1966???
An earlier non BB bracket measures this 1/2"
and the repop 3/8" with the radius a lot tighter than the original.

Wayne was your measurement a 1966?

Ron -- the RH bracket in my pic (1/2" offset) was donated by someone converting a '64 and a '65 [327] to resto-rods, so it has to be one of those years. On my '65s, the bracket is missing on one, and the other tabs are either snapped off or bent beyond meaningful measurability .

Wanyne I know how that goes. thanks.

Anyone out there with a 66 or 67 bracket for measurement???

Ron,

The AIMs show that these two brackets had the same part number for 1964-1967 (3846937, 3846938). From 1964-1966, the RH bracket (3846938) is labeled simply "Bracket", while the LH bracket (3846937) is labeled "Bracket Asm." (presumably due to the weld-nuts).

In 1967, both brackets are simply labeled "Bracket", the LH bracket is no longer labeled "Bracket Asm.".

I will check mine and get dimensions if I can find them.


Edit: For 1964, these brackets are found on 1 Bolting & Welding, Sheet B2, Items 8 & 9. For 1965-1967 the AIM page for these brackets is essentially the same, 1Boltweld-B2, Items 8 & 9.

What is the correct finish for these brackets?

Joseph,

Pages 259, 324 and 387 in the Adams book show the underside of 1965-1967 Corvettes. The brackets look like they're painted black, probably dip-primed or flow-coated. If so, John Hinckley has said that dip-primed parts have a higher gloss (i.e., semi-gloss) than the blackout paint used in the engine compartment and elsewhere.

What type of rivets are used to secure these brackets?

Joseph,

The '67 AIM (UPC 1Boltweld-B2) shows the two brackets are secured by item 3 Rivet, GM 3828548, a flat-heat aluminum rivet, 17/32" dia head, with a shaft that is 3/16" dia x 7/16" long. Doc Rebuild has information on this Rivet on p. 95 of his catalog, and shows a photo of the GM blueprints on his website.

Joseph -

Looks like the photo below - this same SOFT aluminum rivet (3/16" dia. shank, 17/32" dia. head) was used for hundreds of body riveting applications, in many different lengths.

Thanks guys. I appreciate the answers. I'm trying to get the car finished for the 10/21 Pennsylvania Run for the Ribbons Chapter meet in West Chester, Pa.
