Is the mopar fuel sender part # 4051004 the correct non-linear sender?

There was a post on this site that listed Wolf & Company as the place to send your original fuel sender to for refurb. I don't now anything other than what I've read about the company. I am going to contact them this week about a 72 Duster sending unit that needs to be refurbed. I'll post what I'll post what I find out.
