Hi Josh,
no he's done a lot more conversions. Take a look at his website - pictures show only some of his conversions:
Bilder - Oesterle Automobile
And to put it in a nutshell, he's not the kind of guy who wants to share his knowledge.

It's not a one person company.

So don't be pissed if he didn't respond. This is just the way it is.
Regards
Markus
