I don't think the one on Ebay is an NOS one as I heard originals had 4 holes in the vent caps not one like the repros had.
inherited a 69 roadrunner from my grand pop.

I don't think the one on Ebay is an NOS one as I heard originals had 4 MORE holes in the vent caps not JUST one like the repros had. Spot on fuelishnsilly  Mike an original from a first gen Charger survivor (red cap) versus the ebay claimed nos yellow cap. (hate posting this, afraid a future seller may modify the cap with five holes but if the do there's something else on the cap (and battery) they can't modify that I'm not telling or posting......so there

A12,
Ok, so I was wrong. Looks like it was 5 holes instead of 4 like I had heard someone say at one point. Do I get any points for being close? lol

So I bought Joes ( 70gtx440dana ) dead battery.
The thing that got my interest was that the caps were not glued on!
Joe also told me that when he removed the caps it looked red inside?
My thinking was maybe it's a battery in a battery?
So today I started working on this battery shown in my fist picture.
My second picture shows the battery with the caps removed.
I also saw the red down inside there?
I found a seam where the battery was put together.
I started tapping it along this seam and it finally popped open!
I have it shown in my third picture.
The battery case had cracked where the top was glued on.
But it was low enough not to show when reassembled.
Now we can see what the red was from!
Two small batteries wired together and then to the terminals.
I couldn't get the batteries loose so I had to cut the bottom out.
I show the batteries out in my last picture.
To be continued!
MJ

So now I removed my PC925 from my other battery that has glued on caps and attached the cables from the lid of this one.
I show that in my first picture.
Then I got some Styrofoam and made some padding to hold the pc925 in place.
That is my second picture.
I got it all back together and ready to install!
Shown in the third picture.
The last picture shows it installed in my Superbird with the caps off!
When you look inside on this one you see the side of the PC925 and it's black and looks good in there!
I wanted one that looked more correct and now I have it!
Thanks JOE!
If anyone out there has another dead red cap group 27 with removable caps I would like to get another.

MJ John, Glad I could help out. If I had known it would be so easy I would have done it myself. I had seen the other posts where guys had spent hours carving out a donor for the conversion. Did not want to deal with that. Take care! Joe

Joe,
It's not as easy as I made it look in pictures!
That first one that I carved out was a pain!
But I learned a lot from that one and wouldn't do another one of those!
But I am curious as to how those 2 motorcycle batteries started your car and how long did they last?
Thanks again!
MJ

Seeing that we're on gutted battery projects, I recently cut open my AGM Turbostart gas mat repro battery (group 27) to set it up for a battery within a battery senario (I had gotten 11 yrs of service from it, not bad!), I cut the top of the battery off, leaving the bottom intact, I cut it off where it looked like it was seamed, my end result will be to have the bottom section of the group 27 act like a battery box to contain the hidden battery as well as shield it should it leak/gas out/vent, thus saving my engine compartment from any mess, I plan on attaching the top of the group 27 to the hidden battery with a mechanical buss attachment rather than cables, the battery hold down will act as a hold down to not only retain the dummy group 27, but secure the surgically altered top to the base/box as well....
here's what the gas mat repro batteries look like inside for those interested ...

MJ John, I picked up the battery second hand from a guy whom decided to restomod his 71 RR after originally restoring it. I believe he used the battery 2-3 years and I used if for 3 seasons. So it lasted approximately 6 years. I must say i did not maintain a charge as well as I could have during the off season. I may have a gotten another season or two out of it with proper maintenance.

Mike Mike, I you still have the top as it was cut off could you post a picture looking at the bottom or inside? It looks like cutting the top off makes it a lot easier to remove the cells from the bottom! It took me a long time to carve the cells out piece by piece from the bottom! Thanks! John
