Keystone Kustomags - Which Center Caps Do I Need?

Last week I bought a pair of 4" Keystone kustomags in the 5x4.5" bolt pattern. They have an aluminum center with a steel hoop and the spokes go to steel hoop, not connected together like the Keystone Klassic. At one point the rims were painted black and someone installed a pair of painted Cragar caps (the rear wheels were 15"x10" Cragar s/s rims). I will be stripping the paint off and replacing the caps - my question is what Keystone caps belong on the Kustomags? I've seen some wheels with the nice script "K" and some with a block-lettered "K" with Keystone written underneath it. Here's a picture of one of the wheels when I bought them:

My Kustomags have the block letter K with Keystone spelled out below. I've seen the script K cap in ads but I've never seen one in real life or even a picture of one that wasn't an ad, I'm starting to wonder if they even exist.

Keep in mind that there's also a block letter K center cap that looks similar but was made to fit the Klassic wheels, the Kustomag one is flatter and has a wider chrome lip around the outside edge like the Cragar caps have.

There's also some spinners that fit on the Kustomag and I'm trying to complete a set right now but they're hard to find.

 

Thanks squablow - I've mainly seen the Keystone Kustomags with the block letter K (with Keystone spelled out below), but here's a link to the center caps with the script "K":

Thanks for the tip on the different size Keystone caps, I had not clue they came in different sizes. I would like to track down some caps in really nice shape, but if the wheels don't clean up well I might have them powdercoated a magnesium-grey color.

Thanks!

I'm bumping this one back up, i finally found the motivation to finish sanding my Keystone Kustomag rims and will hopefully will be painting them soon. I found one center cap a while back, and am looking for another one (driver quality - decent paint around the large "K", light peppering is fine). Dimensionally they are the same as the standard Cragar S/S center caps 9090 style). If anyone happens to have one kicking around, please send me a PM or reply here.

Thanks!

The rim pictured isn't mine, but is identical style and center cap - although my center cap is painted black around the large K and keystone script.

 

I've been looking into the differences in a Kustomag and Kustomag Klassic. It appears they're essentially the same wheel except the Kustomag Klassic spokes are plated I believe, not polished, and typically have black accents on the spokes.

My '67 Keystone catalog only shows the Kustomag and limited to 14 x6 and 15 x 5.5 sizes. Many disc brake applications require a spacer. By '68 the wheels are advertised as Kustomag Klassics as you can see. The later Keystone Klassic (or Classic) is a whole different product. The wheel's center is 1 piece, welded to the rim. The center cap is tapered, unlike the earlier versions that were the same dimensions as the Cragar SS.
