Deadman, glad this is helpful and thank you to everyone for the compliments. I am happy help. This forum has been invaluable.
I am attaching a DOC file that has the dimensions. THis was exported from Autocad in WMF format. I also have this in Autocad if anyone could use that format it would make things easier for you. Just email me and I can send it to you.
After my modifications the seat will still tilt forward, the seat switch functions. The 1" tube is simply to set the rear height of the seat, you could change this if you wanted a different rake to the seat. Mine sits pretty level with a slght rake down towards the back and I have found it very comfortable. I am close to 6'1" and 200 lbs. I have attached a picture to give you a better idea of how it sits.
If you have any more questions feel free to ask
