Great question, Brian!
The bushings that fit on the bolts for the shackle straps tend to wear out a bit faster than the ones that connect your leaf spring directly to a hanger which is why there are only 4 bushings in the Dexter Heavy Duty Suspension Upgrade Kit for Single Axle Trailers # K71-358-00.
If you wanted to get 2 additional of the bushings that come in this kit then the part # D014-077-00 is the exact same bushing so you just need to order 2 of them as well. view full answer...
Yes, the Dometic 320 Full-Timer RV Toilet # DOM87FR will come with a Base Seal # DOM28FR for installation. It will also include new flange bolts for securing the toilet to the toilet flange. If you wish to add a Sprayer # DOM75FR to make cleanup easier, you will want to change out the parts before you install the new toilet. view full answer...
