I have a 1967 Lotus 51A that I have been vintage racing for a couple of years. It's in very good condition but I'd like to change some of the faults. Currently the car still has the coolant running through the frame and I'd like to change it to an external system. I was wondering if anyone out there has made this modification and could provide a little guidance on the routing of the lines. Photos would be great. In addition, the car currently retains its original Renault gearbox. I have a 4 speed MK9 to go in it but would like some guidance on how to fabricate and route the right-hand linkage. Again, photos would help. Thanks.
