TC Top Plate for Rear Springs

When I disassembled my rear springs which seem to have had difficult history, both the top plates were missing.
I'd like to make two and could use a few dimensions.
What is the thickness of the plate and if someone has one handy I could use the length and the two widths outsider the ears and along the spring sides. The latter should be just over the spring width which is 1 1/4".
I suppose a picture of one laying on a piece of 1/4" grid drafting paper would be good, but I think I can figure it out with just the measurements.
Thanks, Bryan.

I crawled under as best I could and it looks like they are 1/4" thick steel plate. The position of the holes can be matched up with the bottom plate. Once you drill the holes, cut the plate on each side right through the center of the holes and you'll have the right width. But remember to leave the center part a little wider for the two studs that clamp the spring together. The length is the same as the axle tower, which should be around 3.25" if I recall correctly. The dimple will be the hardest part, as it's make on one side and female on the other.

Sorry I don't have one off the car handy but there's a photo on the FTFU website. Hopefully my description along with the photo makes sense.

Hi hope this helps it’s off my 1937 TA , I thought I had one with the studs in but can’t find it ,
1/4” looks about right there’s a slight chamfer looking down the length !
Sorry hopeless with modern technology

Thanks to all those who replied. Yes the bottom plate is a good template and I had guessed at 1/4 inch so now I can proceed. I'll drill the center recessed hole all the way thru and turn a button with stud on it for the centering device.
Cheers, Bryan.
