Recently, I've been working on the wiper system. By getting this finished I'll be able to finalize the fiberglass around the windshield, which will be a big step forward. Originally I wanted to use the Fiero wiper mechanism and wiper arms. However, the link system (used by most cars, including Fieros) turned out not to be feasible as a result of the tight space. Additionally, the Fiero wiper arms are terrible looking. I decided the best thing was to purchase the oem Aventador wiper arms. I'm also going to use the system from an MGB. This uses a cable driven system, which allows installation in tight spaces. The only modification required was to change the wiper posts from the standard straight spline to the tapered spline used by Lamborghini, Audi, VW, etc. This involved a little bit of machining and welding, but turned out to be relatively simple.
I still need to finish mounting the system, but that should be relatively simple.
