I think I have almost everything you need for this. I have a pile of '65-'66 Mustang 4-speed stuff in my Dad's barn. I will be stopping by there later this week - I'll check it out and make you a list if you're interested. Are you looking for a Toploader or a Borg Warner T-10?
Shoot me an email at
krlepp@earthlink.net and we can talk more.
Thanks,
- Kevin
