I had previously measured and marked out the seat pan prior to moving house 3 times to my current address. I am getting back into the project during Covid 29. I finished the hinges for top middle and front locations. Drilled out the locatioins to fitment to the top rail lower rail and spar tunnel locations. I deburred and primed these hinges and did a test fit. I will leave out the seat pan until all controls are fitted for ease of access. I also prepared the middle trim cover c channel in the midldle of the seat ready for fitment. Photo shows the hinges installed I left the seat pan sheet out of pcture.
