The club has had a small run of GX200 engine mounting plates manufactured. These are one of those time consuming items that every build needs.

Save your self a bunch of time drilling and filing by buying a pre-cut mounting plate that you can weld in instead.
Price is $35 to club members and $50 to non-members. Shipping is $15 Australia-wide.
You can purchase via the store right here on the website.
The club is also in the process of sourcing / manufacturing some other hard to find items. So be sure to check back to see if there are any new listings.
