I bought one of the Cycleworks engine stand faceplates and made a simple mod to it so that it would fit my VW/Porsche engine stand.
The two holes that need to be drilled are 8.5" center to center, and they are 2" from each side and ⅞" from the bottom. Photos are self-explanatory.
I haven't tried mounting my /2 engine on it yet (it is still in the bike). If the bolt heads are in the way I'll substitute flat head screws.
looks like it should work really well.
Lets hope you don't NEED to use it anytime soon.
