Mini starter interferes with Z-Bar

My apologies if I am in wrong forum for this question.

I have a '67 Barracuda bracket car, RB w/ 4-speed. After recent trip to track, I noticed the upper mounting ear on the stock style starter was cracked. Reason unknown at this time. Figured as long as I had to replace starter might as well go to mini. Installed and discovered interference with Z-bar.

This is a long time build (early 80's) that has always been 4-speed. For long time was a B-motor car and I switched to RB after destroying my B motor. Obtained mini via Summit (part
# SDM-PCE393-1013.

Question is if I need to go back to stock style starter of did I order wrong one from Summit?

Thanks - any help appreciated.
