Rear axle fill plug finish, brake shoe color codes, drum finish

[430dragpack]

Assembling a '65 HIPO rear axle and am wondering if the fill plug was painted black or bare steel?  Couldn't tell on the original one. Also, is there any color codes on the edges of the brake shoes?  Have seen them on 69-70 Mustang rear shoes. A picture would be great.  Were the brake drums all natural finish or have black out with certain wheels? This is not a Shelby rear axle assembly, but a standard '65 fastback K-code.
Thanks!

Fill plug would have been installed when the housing was painted, so black.

Yes ,brush painted black out on the face surface only (not sides)when deluxe wheels were used. FYI outer front caliper half plated silver because of same deluxe wheel.

This is april/may 66 build, example of original brake lining edges , orange on front, white on rear.
66 Shelby

I posted a period photo of the same, but noticed last sentence saying it's not for a Shelby... not sure why it was posted in the 65 GT350 section?

Did a Hipo rear use the really big fill plug? A friend of mine has a 68 Mustang with a 9 inch someone installed decades ago and it has the large fill plug in the back. Just wondering what it might be out of.

The consensus has been that the 9" housing had a rear fill plug until about May of 67'.  I have the large plug on my 9" housing too, but it wasn't painted. It was a phosphate finish.

Most likely a earlier 67 housing given the dimensional differences between the 65/66 and the 67/70 housings.Ford stopped putting the plugs in the housing sometime in late May or June 67 according to Ford docs..
