Haven't works on a 1st gen Rodoe, but the bushings on 1st gen Troopers are rubber just pushed in by hand. The problem is getting the old bushings out. I found using some heat helps free them.
Jerry Lemond (pm JLemond) has the OEM bushings.
Matt at Independent4x.com has polly replacements. Matt also has replacement bolts that have lube fittings.
