Help with ls accessory drive fit

[Flysocal]

Guys that have made ls motors fit with stock inner fenders what did you use? I was counting on Holley accessory drive to fit but after mounting my inner fenders and measuring it is going to need some trimming of the inner fenders. Not a huge deal but I would rather not. Kwik has high mount brackets and they will clear the fenders will lots of room to spare. What other options are out there? Need to run ps pump and resiovor and sander 508 for my vintage air.
