Anyone know the best way to install bumper strips on a 85 300TD wagon? (Probably the same for many other models as well)

I took of my bumper strips to make some bigger holes in the rear bumper for a new set of backup lights (will post a picture) and I the previous owner use some wire to hold on the plastic strips under the rubber. It was hanging off in a number of places and its always been an eyesore, the dangling bumper strip, in a pinh one time I even used some construction glue to hold it up, but its come off about 2 1/2 yrs later.

It looks cheap to buy a new rubber strip but the plastic clips are $50 a pair. I may try some other way of wiring them back up.

What I wanted to know is the technique for replacing teh rubber strip. Is it to put on the plastic clips first then slide the rubber all the way on from one side? or do you slide the clips into the rubber first then clip ihe whole assembly on?

Thanks again
