Hi, I recently bought a 1953 T100C engine for my 48 T100. Trying to find out what the extra parts are on the C, other than E3134 and high comp pistons. Mine has black

er boxes, don't want to strip it off and then find black is correct. The 1953 parts list seems to be the only one not available to buy in PDF (including on this website). Wondering if somebody can detail the differences in the engine (I don't have the extra cycle parts of the T100C) or advise where I can buy a parts manual for 1953. Mallard
