Just sharing what I had to do to accommodate my alternator mounting so I could have room for belt adjustments.  I combined two different kits from Summit to tailor it to my liking.  Hope this helps others.

Very nice, you didn’t list the kits?  After four different tries, a 15543 works with room to adjust. But you have to remove the valve cover to get it on. 

Sorry. The Summit Kits where as follows

P/N SME-2001 

P/N SUM-420101

I used the lower bracket, upper bracket and expansion bolt of SME-2001 and the Alternator top bracket of the other.  After further research I hear you get brackets for a 327 V8 and it works as well if you want stock appearance.

Not too fancy, but works for me. 

3.75" tall Valve Cover, #15550 belt. Not sure where the chromed adjuster brace came from.

Looks good to me!
