Does anyone know if a new driver arm can be purchased or is it all old? Any interchangeable cars? Does a bolt on style accept or be made to accept another style? asking for a friend lol

On the wiper arm you just need a GM part# and passenger or driver's side to cross referencing it against other GM models of the same era. Some are a bolt hold down and others a wiper puller is a cleaner way to remove. Before removing the old one witnesses mark the blade on the shaft as it will save time lining it back up as reference point to use on the replacement. Dorman may carry new blades, but a used one if available would be fine.

On the bump it looks like it's being pressed over into the seal? May be to high?

All I’ve ever done is use a socket on those. With it being bent over like that, it may be a problem moving it down. Chances are, it was always like that before heat fatigue affected it. If it’s only aesthetic, I’d leave it. I’ve broken more parts than I care to admit because I was “improving” things.

The wiper arm is a bolt on design. You have to remove the rubberized cap on the pivot point to expose the nut. You won't need a puller. Just up and down rocking of the arm base section will walk it off the tapered threads. It is under spring tension, so expect it to kick a little when it is removed.

All wiper arms are designed for the vehicle, and even which side of the vehicle, so you will need another arm for the same application, or from a vehicle that has the same arrangement, like another GM vehicle.

As for the hood bumper, it does look like it was up too high and the hood folds it over. It should turn by hand. Some Amor All, etc., will work on the threads to make it easier to turn.

But does anyone know of a similar car.. is what im asking lol. It needs to kick out the arm a far way from the pivot, most gm applications i know have the arm closer to center, so the wipers usually are shorter on one to not hit it

The rubber hood bushing it used to set the height from side to side of the hood. It's a fine tune part to set proper gaps between panels. So if your hood sits higher on the driver side than the passenger side you turn up the passenger side. But if it sits higher and is higher than the fender, you turn down the driver side. It's made to be turned by hand and is a quick adjust item. It looks like it got caught and pulled on during some underhood work, popping it sideways, then the hood contact points pushed on it and bent it over in an arc.

I'm not sure what you want to do with the wiper arm. Replace it? Make it longer so you can put a longer wiper blade on?

Here's a part# on the wiper arms, note that they have a sprayer on the arm, unfortunately it doesn't say which number is for what side. Not sure if like other manufacturers who have a odd and even number for L and R system, 99 PA.

I've still got the parts car, just saying. We can put as much parts as possible inside a priority mail flat rate box and save a ton on shipping.
