Hi, unless you tapered seat inserts in the wheel you can't use the 3500 S wheel nuts.
You will need sleeve nuts with 7/16" thread or SD1 nuts with a change of stud. Just
clean the centre bore of the wheel and the hub with emery, they should be a nice fit.
Don't forget to copaslip there as well because they can be a git to get off when they
have been on a while.
