There appears to be two versions of these screws, one version with a little extra thread.

My stock is the shorter version. Total length is 0.75" and the diameter varies between std and 0.01 oversize.

References: Page 130 of Canadian parts list. Items 36 H. 35487 has a contradiction (Pin-REAR CS strut to fuse and also Pin CS "V" FRONT to Front fuse??)

  Item 43  H.21916 Pin Fork bolt to REAR fuse

   Pages 22 and 108 of Brittish list. Page 108 refers to replacement parts and oversize parts. Also, reference is made to H. 35487 and its replacement 61816 and 61817

I have in stock the following:

H. 21916 (0.312") standard dia

H. 61820 (0.318") + .005"

H. 61821 (0.322") + .01"
