Weltmeister and maybe some others make a shifter spring kit for 1965-1972 911's that are advertised as high compression springs that "guide the shift lever in the 2nd,3rd,4th,5th shift pattern, preventing accidentally hitting first or reverse". Drilling is required. $50 for the kit.
Has anyone installed these springs? Do they help? Especially on a rapid shift from 1st to 2nd or from 4th to 3rd?
Thanks
