I should also add that the 4 jerry can strap bracket bolts are marked "C".

@ Ralph...I will check on those bolts.

Thanks Michael, I was hoping someone would tell me about the strap bracket - so often missing.

Cheers,

Thanks for adding...on that longest frame to steering gear,a question-or four...
1. Is there a TRS present?
2. Is the thread the same as the other two E C bolts ( 7/16-20 NF ) ?
3. Is the bolt head the same (wrench size) as the other two E C bolts? (5/8) ?
4. Is there a washer under its head?
Thanks


Ralph, hope this helps:
1. Yes
2. Yes
3. Yes

I'm still cleaning up bolts but here are the results so far guys. Some patterns can already be seen.
Thanks for all the great contributions I've had so far.

This is an ongoing project so please drop me a line whenever you make a new discovery and I'll update the spreadsheet.

Spreadsheet V1 available from here:

Removed the rear seat spring bolts this weekend. The markings are quite light but it looks like a large thin A perhaps? Much larger than the A symbols you usually see. Still have another 2 to strip the paint from so we'll see.
Anyone seen markings like these before?

Cheers,

Dave

Steering column support clamp to cowl - C/TR
Clutch and Brake Pedal Pad Assemblies to Clutch and Brake Pedals (Pedal Clamp Bolt upper) - EC
Clutch Pedal lower clamp bolt - A
Clutch control frame bracket (for the Clutch Control Tube) - C/TR
Steering Box/Gear to frame, upper two bolts - EC. Lower bolt to frame (with TRS bracket) - C/TR
Fender/wing to frame brackets - A

Interested to know the markings you found on the 6 fender to grill bolts Paul please - also the length of these not including the head.
Also did you find "A" markings on the 3 grill to frame bolts?

Thanks,

Dave

Dave,

Unfortunately, the bolts from the fenders and the frame to the grill are all modern ones. :( The grill has only a coat of flat black paint on top of gray primer, so I'm assuming someone in the past pulled it off and sandblasted it. At least the bolts holding the headlight brackets to the grill look to be original, nice EC marks on all four.

Cheers
