One part I do remember is getting valve guides from the local machine shop, (used ones were free) that used a 3/8 valve stem, and cutting them up for spacers on the lower bracket. The upper adjuster arm can be made easily with a plasma cutter. Try to get a lower amperage Chev
alternator so the system doesn't have to work so hard. That is unless you are putting in an amp with your 8 track player. I used to make up kits for the homebuilt aircraft guys with a Vega 35amp alt. that fit the Lycoming engines.
I made a harness with an idiot light, alt & brackets for one quarter of what the kit plane companies wanted. I would tell you about the self exciting alternators but I know Alex will read this post and the "self exciting" part will be too much for the old guy.

Hi Barry,

What I was thinking of doing was to copy the base plate of the ebay offering mentioned by Grant. I was then going to take the original U bracket that bolts onto the engine block and cut it to fit the "new" alternator. Once fitted, I would get Bob to weld it to the base plate.

I have a single wire Chev alternator but I am not sure if it is a 10SI 63 amp version or not. Once the alternator is sorted out, a new 12v coil, condenser and single ballast resistors will be added so that I can use the original instrument cluster.

As for "exciters", Alex still gets excited, but doesn't remember why...
