1966 Trim Code Question

I was wondering if anyone knew what interior trim code 98 meant on a 1966 full size? My LTD has 98 on the data plate and I can't find it in the service manual or online. By the colour scheme I want to say it's the Ivy Gold, but that would be 58 in the service manual.

I wonder what the Cologne means. I found a '66 galaxie 500 online with pictures with the code 58 and it's a similar Ivy Gold interior colour scheme. Obviously the print patterns on the seats are different for galaxie 500 and LTD, I wonder if that's what the cologne means. Interior designers create all sorts of weird names to embellish their positions.

Cheers,

Update 2023: I didn't even think to look in the Master Parts Catalog. You can find a lot of answers in the MPC
