89 Project
working on an 89 Sporty, it was completely striped of wiring. I need an ignition module, the parts manual say 32410-86 but most everything I see is 32405-91a. Will the 91a work on the 89 sporty?

Welcome to HDF from the UK. If you have checked a parts book you can also check on-line, which may have more up to date info and parts numbers. Try this website and check that item there.
There are also aftermarket modules available, that may be less expensive and give better advance curves. Stock Harley modules comply with EPA regulations which affect ignition timing. I have used a Crane, but others to investigate are Dyna, Ultima, possibly others, such as S&S.
