I’m currently installing a TKO 5 speed kit from SST in my 80 z28. Everything has gone great and currently waiting on my driveshaft. Thus far the toughest job has been replacing the speedometer cable. A new cable comes with the kit that has the correct end on it for the trans. Issue is it has no grommet. I’ve routed it but wondering what to do about a grommet. I cannot take the cable apart and the old one obviously will not fit over either end. What are some other options?
