You are very much at the split between 74 and 75 model year. I wouldn't be surprized at all if it was a mix of parts on hand the day it was assembled. Could have the last of the 74 rotors or the drilled ones of 75. Could be either switch gear and wiring harness.
Post a pix of the details and a bunch of heads hear can identify what you got.
74/75 differences. Front axle, 14mm 74 or 17mm 75 so front wheel hubs/bearings are different. Solid rotors/drilled rotors. Switch gear/harness. Pattern on seat cover different. Alloy turn signal housings 74, plastic 75. First year of 5sp tranny was 74 and is an albatross. 75 was improved. 76 was resolved of all issues with the earlier production.
The number at the oil fill boss is the VIN. That's why you can confirm original engine by comparing to the same no. on the steering head. The engine number is different and found left front side on the oil pan flange on the crankcase.
Now I see the photos. Switch gear is 75 and have never seen them on any factory 74. 75 switchgear and harness means the factory says it's 75. Front axle diameter should confirm it.
You have an aftermarket deep oil pan.
The center stand is the common Reynolds Ride Off stand. Do take the time to remove and inspect the mounting lugs, clean the threads and hardware. Install the bolts with blue lock tite thread locker. Lube the bushings with grease. Too danged many of those bolts just fall out. Best to keep an eye on those every 30 or 50 operations to verify they remain tight.
