R5 GTX bracketry? If so you can do it with the standard 172 alternator. You may get better access by removing the front bumper and headlight.
no you can't, you'd need a cup alternator. Valver item is a viable alternative,
Bumper and slam panel off, lots of access
My engine is running this setup. You only need to use a smaller bolts to get a bit more adjustment on the bottom bracket.
btw is the dci steering rack you need not the steering column
that gold bracket isnt available available from Stock any more
