Question on sure grip parts

I'll be stopping to look at it tomorrow. Maybe take a pic and post it. I haven't had any luck finding a replacement gear yet. I bought a spool just in case I cant find a gear but I'd rather not run that on the street. I'm not sure how a spool is going to act on the street I have never used or ridden in a car with one in. Guess I might find out!!

I ran a spool with 325 DRs for exactly one weekend; in on Friday evening, out on Monday evening; that was enough for me. Cornering was horrible, and parking lot turns had to be very wide.And,Oh boy; the funky dance the tires did,almost made me cry for them. IMO it mustabin real hard on them.
No more spool on the street, ever, for this cowboy.
