Also here is a link to FRPP instruction pages. Down load the m-2300-k the Cobra R upgrade kit. On the last past is a parts list for the kit. Of interest is the front spindles, hubs and rear disc brake parts. This could help.
M-2300-k instructions
I just reviewed the document and the parts list is on the 1st 2 pages. These directions have been updated since I did my last install. These instructions are very complete and much better than the poor photo copies they sent with the brake kits.
