Funny you should mention the throwout bearing adapter. I just completed
a TR6 race engine for a customer and we used the Tilton flywheel -- a
really nice piece. I had exactly the same experience -- but you don't
know it until the engine is in. After several phone calls to the west
coast, it came to light that Tilton makes the adapter you mention, and
it must be used or the fork is at an awkward andgle and the pushrod
won't connect. Using their $$$127 adapter solves the problem -- which
raises the price of the installation to $450 for flywheel plus $127 for
adapter = lots. Plus for us it was another engine removal. I'm afraid
I'm not a good enough driver to feel $600 worth of difference between my
19 pound cast iron job and the 14 pound nice piece.
