Sorry to jump in on you post wolverinnemac but I have some similar questions...
May have found a donor car with highline, mfsw and perhaps other good bits.
Looking to swap this over to my car with midline, no mfsw etc.
I believe I will also need its steering controller and a small airbag loom?
my dash is 1ko920963b, After reading the sticky I assume i'm looking for 1k0920973b?
Whats the deal with the ones ending in 3 and 4, I have read there are problems with this type?
Cheers
Can older 71 and 72 be fitted in place of the 3's without problems?
