I found a good substitute for the fiber washer at Builder's Square. In the
nuts and bolts department. They had nifty steel washers with a bubber insert.
They were perfect for sealing the hole under the nuts and bolts on the GT6+
I always wondered why the Triumph engineers specified studs and nuts to
secure the rear and middle of the valve cover and a bolt to secure the front.
Must have something to do with clearing the bonnet. Must be the same problem
on a TR6. This weekend I saw an immaculate TR6 with a slight dent in the
bonnet. Right where the front valve cover bolt would be!
