'29 Phaeton 4-dr Left Rear Quarter Pnl

[Klattu1929]

Need some help on the mounting holes in the rear subframe. My body panels (both sides) were rotted out along the bottom. I trimmed and welded on new metal, but the holes in the subframe for mounting the panels I don't know if there are extra holes. Note the three small holes in a triangle at the 21" mark. There are several rivets that along the subframe that don't do anything, don't know if i should drill them out for fasteners or not.

A picture of existing installation showing fastener pattern would be great. I put the tape measure on so if no one has pictures maybe they could give me some reference measurements for fastener locations. And I can weld up any unnecessary holes. I burned the first inch, so ya have to take that into consideration (that's a habit of mine). Thanx for any help on this.
