Motor mount for use in OFNA Pirate 10
 

I want to buy one of Mikes Ofna Motor mounts, but none of them are specific for the Pirate 10. Is anyone familiar enough with the Ofna line to be able to predict which one would best fit the Pirate 10?
Thanks

So maybe I should ask a different question. The Pirate 10 is a fairly rare truck/buggy. It appears that it has some sort of two speed gear set up in the middle - I'll try to post some pics of it. I dont think this is the right thing to have an electric motor run through - so if I were to purchase a complete center diff from some other OFNA buggy - like this: http://cgi.ebay.com/OFNA-Ultra-LX-On...QQcmdZViewItem
would that be a better approach? Then I could just set it up with that particular motor mount from Mike. Or how do the CRT.5 guys do theirs? The Pirate looks to be fairly similar in size to the CRT's.
