Clutch Rod Blanking Plate

[Camarocards]

The blanking plate in the picture below is installed on the firewall when an automatic transmission is installed to fill the hole used by the clutch rod. Was this plate installed by Fisher and was painted when the firewall was painted or was it later installed after delivery by Fisher. Couldn't find any mention of it in the AIM and am trying to determine the finish on the screws.

Thanks,

Bob

I found it in the M35 section of the '69 AIM. That means installed by Chevrolet. Screws are 9419699.

Thanks William,

I was looking in the M40 section since my car has a TH400. My car is a '68 so the plate and screw is shown on UPC M35 A20 in the AIM.

Can't find any reference to what type of finish the screw is. HBC sells the screws in Silver Cad but I'm not sure that is correct. If I look real closely at my screws I find no trace of Silver Cad. I'm guesing it was a phosphate finish.

Thanks,

Bob

AMK part no.'s  20 each for $3.00
B-12048 (Phosphate)
B-12049 (Zinc)

I would lean towards phosphate

Wait is that washer captive or integral to the head?

Jim,

Yes. Found the same AMK info as you did. No captive washer. It's integral to the head.

I'm leaning towards phosphate as well but sure would love to know what the GM defined coating finish is.

Thanks,

Bob
