Great job as usual 2M. Upon eyeballing the left spacer/dust cover, the 72 & 75 appear to be very close. You left out the length of the 74 & newer dust cover. Either you are slipping or am I to assume they are the same. LOL. And we all know what happens when we assume! The axle difference is 25mm and the right spacer difference is 9.7mm. That leaves15.3mm left to fill. The 75 chain adjusters and swingarm ends are beefier, so maybe add 4mm to each side and we still have ~7.3mm. I just may soon attempt to swap a 75 swingarm and 75 front end to my 72. I know I need to use the 75 front wheel, and the rear should just be a matter of using the 75 wheel axle spacers and brake arm. I'm slowly dismantling the 75 suspension.
Thank you for clearing that up. Suddenly, life has meaning again. LOL! I would have had to take my 72 dust cover off to compare. So, I can only assume that the chain adjusters and beefier swingarm ends take up the rest of the length, eh?
