<DIV class=gmail-text
style="FONT-SIZE: 14px; COLOR: rgb(0,0,0); LINE-HEIGHT: 1.3">The engine to
transmission bolts and nuts were originally Whitworth, British Standard Fine to
be specific. 5/16" W or 3/8"BSF (same size, different measurement) X 1-1/4" to
1-5/16" shouldered bolts. There are Five (5) of these bolts.<BR
style="CLEAR: both"><BR style="CLEAR: both">There are two bolts that hold the
starter in place, but they are 1-5/8" in length.<BR style="CLEAR: both"><BR
style="CLEAR: both">Two special "Dowel" Bolts as pictured used to help center
the transmission to the engine, and six (6) bolts, spring washers and nuts. From
the Concours Guidelines...<BR style="CLEAR: both"><BR style="CLEAR: both"><SPAN
style="FONT-WEIGHT: 700">Dowel Bolts</SPAN><BR style="CLEAR: both">The factory
used two dowel bolts to align the engine and transmission components.<BR
style="CLEAR: both"><BR style="CLEAR: both">• A dowel bolt has a more accurate
diameter on its unthreaded portion, resulting in a<BR style="CLEAR: both">more
precise fit.<BR style="CLEAR: both">• Unlike a regular bolt, which is a little
loose in the hole, a dowel bolt fits with very<BR style="CLEAR: both">little
side play.<BR style="CLEAR: both">Without the dowel bolts, the engine and
transmission could be slightly misaligned,<BR style="CLEAR: both">which can
cause premature wear of gearbox bearings and pilot bushes, and cause the<BR
style="CLEAR: both">clutch to "hang up".<BR style="CLEAR: both"><BR
style="CLEAR: both"><SPAN style="FONT-WEIGHT: 700">100</SPAN><BR
style="CLEAR: both"><BR style="CLEAR: both">• The dowel bolts have two flats on
an otherwise round head.<BR style="CLEAR: both">• The dowel bolts go into the
"1:00" and "7:00" (positions top right and bottom left).<BR
style="CLEAR: both">There are two circular countersink/recess in the bell
housing flange at these two<BR style="CLEAR: both">positions which help the
shorter bolt go in farther so that enough treads are<BR
style="CLEAR: both">exposed on the other side.<BR style="CLEAR: both">• The
standard 100 bell housing bolts are 1 1/4" long and BSF threaded.<BR
style="CLEAR: both">The dowel bolts are 1/8-inch shorter and its bolt head is
round with two flats<BR style="CLEAR: both"><BR style="CLEAR: both">To be
absolutely factory original, all Whitworth fasteners should have a black
phosphate, and not a zinc finish as pictured.<BR style="CLEAR: both"><BR
