The one good pic I knew of is gone now. I found a crappy one tho, and these should be your requested dimensions. I've also attached one for the cam tool.

A - 38.55
B - 5
C - 26
D - 12.55


The whole timing procedure for this engine is crappy and there are a dozen points in the process where things can go sideways.

There have been a few different arguments made about using just an M10 bolt ~60 mm long is better/worse/exactly same as using the 303-507 peg. The issue is that the tip diameter of the peg -vs- tip diameter of a bolt could alter true TDC, but I've seen very skilled mechanic with multiple rebuilds of this engine use a degree wheel and verify there was no change to TDC between the two.

I dunno- have no opinion here.
hi,
could you please check for me the dimensions of the 303-748 peg???
