Ok a little update of where I am now....
Started with this (Dash completely stripped):
And this (Panel that craddles the 350z cluster on a 350z):
Old cluster hump has to go so I traced around the hump to cut as little as possible:
Got out the jig saw, mustered up some nerve, took a deep breath and went to town. Ended up with this:
Trimmed up the 350z panel went to the shop where the S14 is sitting. Bolted in the dash cross bar, and my S14/350 hybrid column. Fitted the panel for the right angle and clearance for viewing and tilt steering. Came up with this:
Got some fiberglass resin and some fiberglass matting. With some cutting and fitting, I formed the matting around the areas that needed to be filled in. Held in place by some spray adhesive:
Mixed up the resin and spread her on:
Reinforced the underside using the same method:
Got out the body filler and went to town filling and sanding which is where I am now. This is my first time doing such a task so its taking a little longer than expected but I am pleased with the results I am starting to see. Once I am finished its on with the black leather!
