|Comments:||Problems overcome: I purchased an MSD ignition box before I had completed the
swap. When the time came to install the box, it turned out to be defective, however
the warranty had since expired. I called their non-toll-free number: No satisfaction.
Fortunately the car runs perfectly without the box.
I originally had a T-50 5-speed transmission with mechanical clutch fork. This was very problematic. I'd recommend the use of a hydraulic throw-out bearing and the D&D Fabrications transmission crossmember. The stock Buick starter is not dependable, so I would also recommend the purchase of an aftermarket gear-reduction starter.
Things I'd do differently next time: instead of extending the stock wiring harness, I would get an all-new Ron Francis or American Autowire harness and re-wire everything. I'd also mount the fuse-box inside the passenger footwell.
General recommendations: install a battery cut-off switch A.S.A.P. It makes it that much easier to work on the electrical system. A battery maintainer (i.e. trickle-charger) mounted in the trunk is a real plus: mine is wired directly to the battery terminals and I just plug it in when I store the car. I've learned a lot along the way: plan ahead and don't get too anxious when the end is near.
