If this is true then its new to me!!
Think again, I've got a D50 in my '99. I havent pulled the cover to verify but from everything i've seen the SD's came with D50's up until '03ish. D50's are easy to mistake for D60's. They look very similar on the outside but the D50 has a D44 carrier and D60 outers
