Boy, I really do need to pull these seats out and remove the stock seat sheet metal floor brackets.
These new seats are made to sit on a flat surface, and a lower surface. I have them installed now, on top of the orig. seat floor brackets, which puts the seat around 3" higher than what the stock (or the DAD seats I had) were sitting at.
This is causing my calf muscle to burn while pushing in on my twin plate clutch. I suppose its due to my legs being now, more at a 90 deg angle while seated, instead of being pretty much stretched strait out with the old seats (better leverage).
I must remove the seat floor brackets, and mount the new seats on the floor boards!!
