Need a quick Lehner answer...

I'll be designing my motor mount for the Savage tomorow morning, I'm going to make a universal drop in mount for any Savage that will fit the following motors:

Feigao 540S, L and XL
BK Wanderer 540S, L and XL
Lehner 2240 and 2250

I've got all the dimensions for the Feigao and BK (they are the same right) I just need to know how many mounting holes the Lehner has?

Other than that expect a good motor mount done by tomorow night. I may try and incorperate a nice heatsink into it too...
