I'm joining in here because "Achipmunk" mentioned my name. That may or may not be a good reason for joining in and it looks like between Joe H and 46Sparky most everything has been covered .
I have no reason to disagree with any one about how the grill is made or how the grill is installed, but I will tell you that my grill is held in place with the afore mentioned tabs. The tabs are down each side of the inside of the grill housing. The grill slips into the housing from the front and once it is in and snugged up against the housing front (from the back), the tabs are to be bent over the outside grill frame itself for it to be held in place. That may not be the right way to install it, but is sure is easy and it looks correct. Yes, you have to have long arms to bend the top tabs!
The top trim for the grill is stainless and is held in place by screws across the top of it. That part, as most of you know is reproduced by several vendors.
The side and bottom stainless pieces of the grill housing are made to slip on the edge of the grill housing which surrounds the grill itself. The crank hole cover, which is also stainless slips over or into the center bar of the grill to cover the crank hole. Those pieces are also reproduced in stainless.
The one thing that I don't know is if the original grills were stainless. Mine is not stainless. I do not think it is the original, but since part of the original grills were painted, it is possible the original grill itself was not stainless. The grill was on the truck when I bought the truck 39 years ago. I recently had it chrome plated and it looks good. I painted the sides of each vertical grill bar, but left the front of each bar chrome.
I hope this information is helpful.
Joe
