wiper linkage arm fitment

ive just bought some 12" slip joint pliers,ill pick em up later,ill try them with socket on back,seat removed.If thats no good ill remove dash n glove box,ive had no leaks so ill leave them as im in UK and id need to order them and wait a while.If them bushings were pliable it would be easy but mine are solid,no wonder theyre cheap

I've used these. If you try to force them on with a pair of slip joint pliars, you will break them. (ask me how I know lol ! )

As 4Speed suggested , put them in hot water , install them then use a spray silicone based lubricant on them. As Halifax shops suggested, do the pivot gaskets. I also installed the grease nipples at this time as well. It's a ***** of a job that you only want to do once so do it right!
