Hi Bob
Yes I make those . The kit includes the driver with 2 different arms ( straight and angled) a seat and steering wheel plus steering column. If you want all parts in white ...... I can do that!
I sell them for $50 plus shipping.

I use the Savox SA1230SG servo in all my gas boats. Has plenty of torque and I never had a failure.

FYI
I ordered 3 in- flight needles about 3 weeks ago from
https://www.rcjapan.net/
They have a ton of OS spare parts.
Shipping was super fast via Fed Ex.
