C5 Diff in a Crown car. Cost and what is required?

[Mark Moyer]

My Crown is a 327 with a Saginaw and a 3:55 Spider diff. I want to investigate converting to a C5 diff. Does anyone have an estimate for what it costs to do the conversion myself and what is needed, other than the diff itself?

Also, any recommendations on who to reach out to for advice and parts?

Thanks,
Mark
