When you take into account the motor mount function of the motor plate...

If you run a (CSR pump...a price point in the middle of Summit/Preform and Meziere) trim the cover yourself and fab your own alternator mount, my estimated AEI cost is just over $600

If you add AEI labor to trimming the front cover and their billet alternator mount, the cost increases to $914

Meziere plate - $285
Meiziere pump - $681
Motor mounts - $270
Total $1236
