So, first post here (wooooo) - what I wanted to try asking is if anyone here knows if there's a size difference in the clocks that ended up in P11/12's and the P15's? In pictures, they look about the same size, but I have heard people say that they are not compatible and one won't fit the other. Once all said and done I hope to also add a Philco 802 radio, P12 center dash and clock to my P11. (wish me luck....)

The P-15 clocks are shorter than the P-12. I have one in my car, a 41 Special Deluxe business coupe. I found it in a parts car on a club member’s farm. If you look close, you can see someone (this is the way I got it) took a P15 delete plate and cut it to make a little filler at the top. The P-15 has 3 lines running vertical on the delete plate to match the dash, the P-12 has two.
