I pulled a fiberglass mold from the bottom and then made a relief and bonded it to the bottom of std WIX oil filter.
I have not finish painted it as of yet.

I have been wanting to do it for a while but didn't want to pay 600-900 for a filter to pull a mold from - I ended up with a NOS filter for about $100 6 months or so ago and now wanting one for a 69, recently got started on the project.
I can't believe someone has not done this previously.

What about Decal plans? Computer and graphics with printed cut mask for paint or decal

I have the decal that is available (RED and BLUE) however I am probably going to do the black AC logo like Lloyd did on the filter he made.

Very cool idea firstgenaddict!

Love to see this creativity among those of us in the hobby with enough skilled (or obsession...lol) to do restoration projects like this!

I converted my NOS date coded voltage regulator to electronic and hid the conversion under the voltage regulator lid. Tried everything to try and prevent the regulator from overcharging charging the battery, gave up and converted it.  I also designed and had made another "device" to allow me to run a full roller mechanical cam (current cam technology) and keep the cam float fore and aft to spec yet keep my original DZ 302 timing chain cover.

One other area on the '69 1st Gens I am looking into are RS headlight conversion kits available from Detroit Speed.  They did a great job engineering their kit but the doors open/close too fast compared to the speed of the original vacuum actuated head light doors.   Plus, I do not want to cut another 1.5" grommet hole in my firewall to run the wiring harness between the headlight switch and the electric actuators.  I want to try an retain the proper vacuum hose location and grommet.  My original vacuum relay looks very nice but no longer functions correctly, and my (2) actuators leak and will not pull sufficient vacuum to open and close the doors.  Replacing these two RS vacuum components adds up to about 35% - 50% of the cost of Detroit Speed conversion kit.

Fun stuff!

We ran a solid roller with the original timing cover on the black RS/Z. It had a button though.

When I build my motor with the solid roller CS XR274 R-10 series #12-770-8 from Comp Cams.  I mocked up the build, included a cam button, and tested the fore and aft movement of the cam in the block. The original sheet metal timing chain cover has a fair amount of flex.  The helix angle on distributor gear tends to push the cam forward, so the concern was the stock cover would not limit the cam movement to the recommended 0.008" - 0.012" by Comp Cams. I also invested a fair amount in the valve train as long as it fit under the stock valve covers.  I have been very pleased with the cam.

Under non dripper 69 covers with a felpro thick and thin gasket glue together you can run aluminum needle bearing roller rockers with a .636 lift solid roller...  ::)

with a coat of white paint

Well done James as always.... When I reviewed oil filters several years ago during our 68 restoration I found NCRS after their review and research could not substantiate that the embossed filter was exclusively used and they accept either PF-25. But love what you did and again well done James.

If not mistaken 1968 and early 1969 model year would have had a PF 29 filter, which were not embossed, which is odd as the 1967-1968 version of the AC PF24 (pontiac filter) is embossed.

In the NCRS a 69 and 70 without an embossed filter will lose 5 points for configuration.
The reproduction AC PF 25 with the dime sized circular impression on the bottom will lose 5 points for configuration for 1971-1977.
to be correct for 71-77 The circular impression on the bottom of the filter can needs to be about the size of a silver dollar -
as shown in the center of the mold bottom without the embossing - the center circle size is easily larger than a dime.

Thank you JIM, exactly what I was referencing.

The small impressed circle loses configuration points for 71-77.
The large one is correct, but to get 100% of the points the top crimped band should be bare steel/same with the embossed version top crimp band is plain steel no paint.
