Hello Martin, I have leather seats, 4 pt harness and a lowered floor. I have fitted the RHS seat and harness. It seemed to slot in fairly well. The put the seat right back, put the front bolts in (the lever goes under the bar in the cockpit). I then moved the seat forward and did the back bolts. This was a bit of a squeeze, but I managed to get an Allen key behind the seats to hold the bolt as I torqued it up. The harness needed to be fitted before the seat and I needed help from Derek to understand how it worked. However, once explained, it was straightforward. (I'll blog about it shortly). I managed to do the back lights this evening. However, I still can't solve the non starting problem. I'll be interested to see how you guys get on with turning the key. My lighting arrangments seem to work OK except for the RH front repeater. There is some electrical resistance between the wingstay and the chasis. I figure that once I lower the car on its wheels and bounce it around a bit the connection might improve. good luck with the seats. Simon
