Hi there!
The rims on my 74 DT360A unfortunately have quite some lateral and vertical runout. I wasn’t able to measure it yet, but at least at the front it‘s easily visible, that it exceeds the 2mm limit. While driving on a smooth road at around 40mph, the vibrations get pretty intense. I‘m not sure if it‘s the spokes or the rim itself.
I don’t have much experience with spoke rims, I remember to have read somewhere that you should avoid adjusting/retightening spokes that old. What’s your opinion on that? Does someone know the exact length of the rear (18“) and front (21“) spokes or where to get them? Maybe some newer models used the same length.
Hello Leon
I think it's ok to adjust and true the original wheel spokes, but knowing that if you fail to improve the runout, then you may have to go shopping for a new set. Afterall, why not try if it's already bad?
If you need help, there are "How To" video's on the internet
The FRONT WHEEL has two different spoke "head angles" ... (18 Inner & 18 Outer) ... but they are all the same length . . . 229mm.
I have the front spoke set for $120. + shipping . . . See picture below:

The BACK WHEEL has two different length spokes (18 Inner & 18 Outer), and it also has two different "head angles". This means that there are four different spokes used on the back wheel.
9 short Inner spokes, & 9 short outer spokes = for right / brake side
9 long inner spokes, & 9 long outer spokes = for left / sprocket side
Unfortunately, I don't have this rear set . . . and I don't have the measurements either
NOTE: There's one rear set on eBay USA, but very expensive . . . eBay item number: 156337303624
