Thank you Toon or was it maybe to Rubino!?
And yes, Rubino, I've the complete plan in my head!!
I build the car allready a several times in my imagination or dreams, what you want.
When I'll start with the car I will let you know how things are planned and what you must do to transform an 850 chassis into an OT1600 spider chassis.
You are a welder and fabricator, I think, so that part will be no problem for you.
I'm only a teacher(science) with a lot of free time. This week no school, so working on the OT1600 and the new project, I hope!!
Groet,
Fred
