These are made to order, depending on the desired  angle of your engine, they can be machined at different angles. Unlike other mounts which just have the back side of the mount angled, the through bolt holts match the same angle to prevent the bolts from bending. 
 
Depending on your set up, four engine mounts should be used. 
 
A 2 degree angle is what Schiada currently uses on their day cruisers. 
 
These have an approximate 4 week machine time, since there are so many degree options are available.
