I’m installing a new crest on a restored front mudguard that has no holes drilled in the top, and I’m not sure where to drill! Could someone please let me know what the correct distance is from the front of the mudguard to front of the first hole (or to the front of the crest) on a Sprint 150 / VLB1T?. Then at least I will have a rough idea where to start drilling. Many thanks, vielen Dank!
