So... Who has got the definite half doors installation guide from scratch???? And as B1THN, with pictures would be better. Sorry for the hijack. I'm pondering in making some or buy half doors, in fabric not hardshelled. I don't have a tonneau so need to put some poppers on the car. The problem is, I found that at least one, if not all poppers, according to the locations on the Caterham K-Series build manual, will have to be secured on chassis tubing. Is this correct? K-series build manual Section 14, Page 6. My car is a K-series SV, if it makes any difference. Thank you in advance!
