69 and 70 window regulator interchange
Permalink  

I see when looking at power window regulators, the 1/4 regulators are the same between 69 and 70. However, the front door regulators do not interchange. 69 has it's own number, 70 has it's own number. Does anyone know why, or if they actually will not interchange?

I believe there has been discussion here about door interchange but I can't recall that the window regulators were discussed.

I am actually asking for someone else anyway. The manual regs also show in the interchange as being unique to each year.

That would be great if you remember in the spring. Hey wait, it was spring here again today, +8

I can tell you 69 vs 70 door sideglass in a 2 door HT is different. They have different mounting holes for the track mounting. Not sure about the 1/4 glass. Haven't compared the two. The GM numbers are different though.

 That could be the explanation Carl.

I am wondering if a guy can use 69 parts if he changes the whole thing, regulator/tracks/window.

The one thing that could stump the process here is that I'm looking at 70 USA glass (bonny). But I highly doubt any difference between 70 Cp and USA sideglass.

I bet you could.

Carl, above you said the 69/70 1/4 window regulators are the same.  What part # did you come up with?   The set of rears I got from a 70 Impala have 8727480 & 8727481 painted on them, but those #'s don't show up in my parts books.

Often the part numbers on the regulators don't exist in the books. Then, out of the blue, you see a set of regulator numbers exactly as listed in the book. Go figure.

I figured that might be the case.
