Just wondering if handbrake cables came in different lengths for type 1s. Reason I ask is that handbrake cables on new(second hand) gearbox seem to be shorter than previous ones even though axles seem shorter.

Yes, there are several different types of Beetle handbrake cable.

ive got a new pair thats too long... what length are yours?

VWHeritage used to have the lengths and years models on their shop website. Just drop em an email to ask if Mick Motors can't help.

Always change in pairs as a new one will load the old one and make it snap a few days later
