Sweet rack... that must have cost you a pretty penny.
Just use your model number and refer to the pics in the Ultimate Sears Spaceliner Reference to see exactly how the bike should be equipped. If I remember correctly, you once quoted the model number for the deluxe (46902), and if that's correct then your new rack is the right one for the bike. The grips should be black, though. Sometimes they have Sears stamped on the ends and sometimes they don't. The girls/ladies bikes used white grips.
All you need after the grips are the correct seat and pedals and you'll have a perfect example.
Here's the direct
link to the pics for the 46902 Deluxe model.
