Grill Holes Help

After I looked at a few other grills I do not see that they have these holes like mine. With my 63’ WilLy CJ5 Frankenstein jeep I am now wondering if my grill doesn’t match either. I’ve posted about my radiator/vent issue as someone fabricated the spot where the hood bars connect to gold the radiator but not the grill/vent/shroud (whatever all that is called).
Did these holes show up on a certain year or?
Plus what bolts or fasteners go there as I have not found a Jeep with them.
Thanks.

 

That looks like the hinge mount points from an M38A1 grill.

This may explain a lot as the engine bay bars look like they do not appear to connect on these models.

 

Thank you! I think you got it!

 

What attaching the bottom of the grill to the chassis? Yes, the early A1's used the hinges, but by '53 (mid-year) they used the center bolt with big bushings to a mount on the crossmember, as adopted by the whole CJ5 range.
Are those fabricated brackets running down the side of the chassis holding the bottom of the grill?
I understand the center mount was neccessitated by too much chassis flex twisting up the front sheetmetal on the early A1's.

Yes i think those brackets are from a PO, but i am not too familiar with Jeeps and all their connections/parts etc.

I have posted before about trying to figure out why the frame on the back does not align with the back gate/tub. One suggested that my frame may be a 3b, but now thinking it may be a M38. It is registered as a 63 CJ5, but since the bodies are so close it may have just been a guess when whoever was registering with with the DMV.

I want to start trying to figure out any other markers that can help me with deciphering this Frankenstein.
Anyone's tips etc. is appreciated. Are there any other markers, etc. i can look for? I tried to find the stamping on the frame but i assume i cannot see it unless the tub is off.
