67 J56 Brakes

[Stephen L.]

When purchasing a 67 Corvette with J56 brakes it was mandatory that J50 power brakes also be purchased (NOLAN ADAMS).
Did both J50 AND J56 line items show up on the window sticker?
J50 has ECL's that correspond to engine configurations while J56 has only 2 ECL's (defined as AA for L36,68 71,89 and [AB for L88]) which appear to be "one size fits all" engines.

The various ECL's probably identified the unique fittings etc req'd for the various engine configurations

Steve,

I have a 67 order copy that has J50 as a line item but the car did not get J56.

Later I'll look to see I know I have another 67 window sticker to see what that car was ordered with.

For 68-72, both J-50 and J-56 were shown on the window sticker and build sheet when a car was equipped with J-56. I expect it was the same for 1966-67.

Steve -

I have several '67 window sticker images for J-56 cars, and they show both J50 and J56 as separate line items.

Thanks all for the information. I kind of thought that to be the case but wanted verification.

Re: 67 J56 Brakes

Hi Steve. Why hasn't that control broken yet?

My sticker has 02J50AA listed just above the 02J56AA as the last two items on the sheet. The exp date of prod was 9-30-66.

Are you looking for some radio repair work?? The control is hanging in there and there isn't any static in the volume control either. The ultrasonic cleaning did the trick.
I thought of a way to repair the switch that controls the light in the radio. Mount a small 12v relay inside the radio that is controlled by the on/off of the radio and run the light circuit thru it. That may open up more generic volume controls to the Corvette application, while maintaining the unique light feature. Just need to find a small relay

Heavens no, I keep hoping the radio work will slow down Steve. There's no time for driving, flying or even snoring. Heaven forbid that I should ever run an ad!

Go down to the R Shack by you and grab a 275-249. You can epoxy it to the underside of the rear lip of the tuner frame behind the controls - two will fit perfectly in that area.

I used that same relay to do what you described in a 57 Wbar recently to keep the repair cost down for the owner. If you let your working switch half control the relay, you can use the heavier contacts of the relay to switch the power and the lamp. That takes some of the heavier current flow off the weakened/corroded/hardened grease switch contacts and we won't have to get high on the alcohol fumes again. HEH

Yes, lots of controls with that single switch and the correct wiper values are still out there. But too many have the plastic tone shaft instead of the brass in the vette. But they meld pretty easily with some patience.

Nothing else new here Steve. Just getting old (un) gracefully... stay away from those white Simpsonville cruisers!

Stephen -- here's an answer to the J50 ECL's when paired with J56. GM Canada import records show a '67 coupe with automatic trans, 390 hp engine and heavy duty brakes (salesman had to be really good ). Appears that the J50 ECL's when combined with J56 used the same 13 codes as without J56, depending on other options, as you've said.

This particular car, #15346, has 02J50DA (L36 w/M35, per Noland); 02J56AA (with L36 [also L68 implied] or L71); 02M35AB (w/L36); 02L36AA (no exceptions).

I assume the window sticker would be identical.
