MoriniMan & Mister Towed: - Thanks for the replies gentlemen.
I'll form a plan when I know how well my frame lines up with the chassis.
It all else fails I will just have to paint/seal around the prop. shaft, etc.
Redratbike - Thanks for the courier info.
Although I hope collecting the heater might help me sell other small bits.
Hopefully I'll get a large chuck of my domestic chores done this weekend.
And with a bit of luck still have time to test fit the frame.
Have a good one, Paul.
