I have an extra steering arm bracket. Purchased it off of e-bay and then found the one I picked up the year before! (We are in Kenosha.) I may also have some brackets. The gear shift cable attaches to the gear shift lever inside the lower cowl. There is a rubber plug in the front of the cowl for this. The throttle cable parts attach to the pivot on the exhaust cover and attach to the throttle assembly. The cable also enters via a rubber plug at the front of the motor, this case, it is just above the linkage from the tiller handle.
