Lotus Seven S4 information

[mrvman]

I am new to the forums and long suffering Lotus owner. I am considering purchasing an S4 Seven Lotus in the USA, If I can find a project or car. Questions, no windshields frames available anywhere? Seats, no seats available? Is there a vendor that specializes in the S4 Seven? Workshop manual parts list, does the Seven Manual cover the S4? Is that manual still available? S4 heater, what car does it come from, Spitfire? Rocker switches on instrument panel, where are they from? I am sure more information will be needed at his moves along. Now to find a car, prefer a project. Thanks in advance. Steve V. In Arizona USA
