Nova .21 vs .12 bolt pattern

[Brandon Atwell]

Do the Nova engines share the same bolt pattern or do .12’s require skinnier mounts?

Thanks guys!

12 case and 21 case are different sizes, if that's what your asking.

Right so the .12 wouldn’t fit into .21 rails/ bolt pattern because it is narrower?

If so yes that’s it, thanks!

Yes it's narrower

Spot on. The diagram below is posted on my website and gives you most of the dimensions you guys need. I posted in pdf and image formats. Thanks.
