Pfaff 138 needle bar help.

[SalsaJoe]

Hi, fellow sewers.

I've got a Pfaff 138-6. iI's new to me and has what's called a cording foot which is a twin needle.  It looks like the last owner was just running a single needle on the right side but this does not allow for it to zig zag correctly. I've done a decent amount of research and it looks like I will need to replace the needle bar, feed dog and plate. All the parts I've found BUT  the needle bar.

Hoping someone might know if A) in fact I do need to replace the bar, can I use one from another model and if not any dealers in the US that might have one.

thanks in advance for the help

I know the 138 isn't a super popular model and I'm a new member to the form so I thought I'd update for anyone in the future. I've used this site for many other machines and it a great resource.
I contacted Dürkopp Adler America in Atlanta and it looks like many of the parts for the 138 are no longer made in Germany, but I was lucky enough to find a used 138 needle bar on ebay with needle clamp so I should have what I need to get this back to standard needle setup. I've never worked on Pfaff 138, most of my experience is with Japanese machines. If anyone has a service manual for the 138 or link to info on changing out a needle bar please let me know.
