Stainless Steel Fasteners for the ZF

I am replacing every piece of hardware possible with stainless steel in addition to painting each major part.  I want the tranny to be easy to clean, look good, and reduce corrosion potential.  I haven't polished each stainless steel bolt as I think it's not necessary for my tastes.  Here's a list of hardware available in stainless steel for a 1971 ZF 5-DS-25-2 transaxle:

M6 socket (allen) head bolts in the following quantities:
2- M6x50 for shifter cover
1- M6x30 for the shifter cover
2- M6x20 for the shifter cover

M8 socket (allen) head bolts in the following lengths and quantities:
14- M8x1.25x25  for lower cover
2- M8x1.25x40 for case halves
4- M8x1.25x50 for lower cover
1- M8x1.25x60 for case halves
1- M8x1.25x80 for case halves
1- M8x1.25x100 for case halves

Lock nuts in the following quantities:
2- M6x1.00 for the shifter detent cover
24- M8x1.25 for the rear cover, case halves, and shifter shaft end cover
25- M10x1.50 for the side covers and bellhousing

Flat washers:
5- 6mm standard flat washers for the shifter cover
10- 8mm standard flat washers for the shifter shaft end cover, and the case halves
5- 10mm standard flat washers for bellhousing nuts

Copper washers:
15- 8mm washers (5/16" washers are equivalent) for the end cover
20- 10mm washers (3/8" washers are equivalent) for the side covers

Please note that the use of a good anti-sieze thread lubricant is recommended.  I use a copper-based anti-sieze thread lubricant.  Stainless steel tends to gall & cause corrosion in aluminum and the anti-sieze will help to reduce that potential.
