If I bought a 94 sc300 window regulator would I be able to put it in my Soarer?

If not, where would be a good place to get a regulator at for soarers?

 

Here are a couple links, if you decide to take on the window regulator repair. Otherwise, any place you can find one.

^^ All that Tallyhoe posted above.

If you go by the same model year and mid-year revisions you *should* be able to use the appropriate SC window regulator *for that revisions series SC* in your Soarer. These *should* be directly compatible though I don't know if anyone has confirmed it yet. But there isn't anything fundamentally different with the doors between the two cars and so I cannot see any reason why this wouldn't work.

But you need to make sure you match up the right chassis series revision on the Z30 Soarer side with the same series revision on the SC side.
