Bearcamp you can get the seat on e-bay there is a couple of different vendors.One sells for 30 someodd dollars and there is another for $24.99.Look at the project forum at the thread called first build that has the $24.99 seat on it,comes with the springs.Looks just like the one on the Whirlwind I have.You can also get motor plates there to.They are universal just depends where you weld the for the type of motor you have.Also manufacter supply or Northern tools has the motor plates.:weld:
