Reply to "Seat Modifications"

Peter, most of the right seat interference comes from the part of the bulkhead bulge that covers only the alternator. By repositioning the alt back 1" and driving it off the unused sheave of the A/C pulley, then notching the steel bulkhead cover as was done to the seat, the area of the right seat will be 'flat' against the rear firewall. The bubble part of the upholstered cover is separate from the rest of the big rear upholstery and can be pulled loose so the big bolted-in panel can remain in place while you remove only the (modified fiberglas) bubble-upholstery for front engine access. Most Gr-3 racers were rigged this way- possibly at the factory. The whole mod looks stock but is far more comfortable to drive or ride.

Alt. repositioning is simple, done with hand tools. You saw exactly 1" off the rear of the alt boss and use that as a spacer in front of the boss to mount the same alt 1" closer to the engine. No wire repositioning needed and the factory mount bolt fits. The alt adjust strap fastens to the rear of the same boss as stock, using the same small bolt. All this has been the subject of numerous illustrated Newsletter articles over the years. Last, take an old vee belt, cut it to exact size and use that as a model for your new belt. Vee belts are available in 0.060" increments but the way they're spec'ed is not straightforward.
