Myself and my neighbour used a Metal lathe to make up all 16 spacers that are needed to ensure the suspension is aligned correctly.
Made from 316 stainless steel, with a 1/2" bore they should last forever.
Each one is a slightly different size to take into account subtle differences in the geometry of the suspension.
I have a good length of bar left, so if I ever need to adjust them, we can machine some more of different sizes.
I also got to work on the tunnel sections again, I have cut the hole in the rear bulkhead, given the density of things that need to go through the tunnel i elected to cut out the complete hole. Then i can move things around to find the optimum way to organize the tunnel.
First thing to try is to see if the gear linkage cable can be hidden in the tunnel and still connect to the gearbox.
One cable may need to come out of the tunnel early, time will tell.
