69 1/2 roadrunner upper core support plates, for hood pins.

69 1/2 roadrunner upper core support plates, for hood pins. - 02/20/24 11:48 PM

I put a fiberglass hinged A12 hood on my 68 gtx clone. I would like to put in these upper radiator support plates for the 69 1/2. For my hood pin mounting. Question without having a 69 in front of me are the plates in the picture part of the inner fender? I can't find just the brackets listed or used. Or a picture of your hood pins on a 68 would be appreciated.

Thank You. That is much appreciated by the way. And thanks for pointing that out on the fenders. I may need to fabricate something similar.

The "pad" for the '68 B-body Plymouths is smaller than the '69 and still haven't figured out why? But I do know they moved the ignition timing decal to the left/driver's side which IMO is the wrong place when setting the ignition timing per the decal. With the larger '69 pad it blocked part of the ignition timing decal so it got moved in '69. '68 show judged B-body Plymouths should be docked points if the ignition timing decal is on the driver's side like the '69's grin grin

Yes I too think you will have to fabricate something to get the pins in the correct locations.

The '68 "pads" and why the ignition timing label was okay to put on the side that you normally time the ignition on. Closest to the distributor and crankshaft flywheel timing mark. At best on the '69 maybe that should face the ignition timing label toward the passenger's side wink

You are best off fabbing a bracket to hold the pin in place as you can't just cut those brackets off a 69 fender and put them on a 68. I had a 68 front clip grafted on my 69 RR decades ago and there was a lot of fab work to remove the 68 corner brackets and graft in the 69 upper core support ends so the 69 fenders were a bolt on.

I Thanks for the replies. I always appreciate the advice on this website. I will fabricate some brackets and post some pictures. Not a restoration in any way. it started life as a 318 2 bbl sport satellite. I purchased it as a GTX clone many issues but a rust free car. Finally after 6 years I am going to body and paint this weekend. i'm 66 this is my last major project.

If you could find a couple 1969 fenders, usually even some totally rotted out ones will have the "ashtrays" still intact.

There are a few spot welds holding them on to both styles, cut (tiny belt sander) or drill the spot welds and they interchange.

I converted one Plymouth fender from a 68 to a 69 using a rotted out 69 "parts fender". Besides the side marker hole and the ashtray needing to be
changed, the '69 also has a small welded grille mounting bracket that needs to be swapped over.

It would probably save time to just fabricate something, and my hat's off to you for trying to install the pins in the right place.
(Can't tell you how many cars I've seen with the pins installed closer to the middle of the core support, nowhere near the factory location).

Good luck

That's a mean-looking car up...
Being that it's a modified, non-#s build - not a strict restoration - why not just use the '68 hood bumper location for the hood pins ?
Damn near nobody would have an issue with that, if that matters, and the location's close enough to "pass".

Have to add a plate to the '68 as the hood pin hole and plate on the repro or OE Lift-Off-Hood are in front of the radiator support. The LOH (hood) pin holes will not align with where it is possible to mount the pin on the '68 pad.

I will post a picture once welded in. This is what we came up with.
