951Dreams

So I'm looking at an 86 951. The color was easy:

LY7Y - Zermatt Silver Metallic

However the interior code is LR. I can't find even a whiff of a mention anywhere on the Googles. Anyone seen this or have an idea? Looks tan. Not LQ tan, but real tan.

Here's the Options codes:

I39 ????????????
I89 ????????????
018 Sport steering wheel with elevated hub
220 Locking differential
474 Sport shock absorbers (Bilsteins)
533 Alarm system
650 Sunroof
983 Leather seats front and rear
C02 Equipped with catalytic converter

anyone seen the I39 and I89? I've seen a number of stickers with "I" codes on them in my searches. Not these, but others. None of which are on any code page I could find. Ideas? Anyone know anything about these "I" codes?

Thanks!
