8" to 10" brake conversion

hello

I have a 1963 VBB2t that has an 8" to 10" conversion half done.

your part number J50015100 is a complete kit and I was wondering if it is possible to buy the following

parts only

2 rear brake shoes ( 2 anchor pins on hub)

1 front axle shaft and speedo drive

I have a second engine which has 1 anchor pin on the hub but I would perfer to rebuild the orignal

I would appricate any advice on the issue
