Title: I.D. these plates please??

These plates came with my A7 project. Either I'm orienting them wrong via stupidity, or they aren't the right plates.
Im working from a '54 swinging arm frame. The holes don't seem to line up with the engine cases, or the frame.
I could provide some center numbers if needed. I thought perhaps someone could visually identify them.
Maybe they are for a plunger?
Thanks in advance!

This might help. It looks like you have the correct ones.

The two with the offset go on the left side, you should be able to see this in the pics.

Okay, I see how the are placed now...
Wow. Not how I was trying to do it.
Thanks a bunch. When I get out to the garage, I will double check.
It is sort of mysterious bolting up something that I didn't take apart,
or that I have never seen together.
I will mock it up later, and post the pics to make sure.

Looking at your frame mods, two things come to mind. 1. the rigid BB32R factory frames which were based on the swingarm frame front half typically had a vertical tube around 6 inches forward of the back axle, probably have a factory drawing on my other computer and theres probably a copy on this website - but this tube on each side helps stiffen up the frame
2. there was a forum member looking for some footrest tubes recently and you appear to have some spares  ;)

Look forward to seeing progress, what style of build are you working towards?

have attached an image of Bender, my own replica rigid frame as reference which is documented in the the road rocket racing sidecar.
I look forward to following your build!

so this isnt about me  ;) have attached an image of the late Kenny Eggers on his team wrecking crew, Daytona BSA for 1954, which my bike is based on a replica of.  (but with 16" wheels and a sidecar  *whistle*
The daytona bikes (which absolutely cleaned up in '54  *smile* ) used a converted toolbox as an oiltank. Its very neat and keeps the weight low, while also retaining the rigid plunger style.
I got a replica toolbox and modified it to suit.
