Thanks, just read through your Blazer build thread. Very impressive. So the ball cannister is unique to 4x4 or just tthe bracket?

Thank you! Still working out bugs but no regrets.

The bracket is unique to 4wds w AC whereas that plastic vacuum ball/canister reservoir is also seen on 2wds. The plastic example replaced an earlier model year (pre 71?) piece that was metal and resembled a soup can.

Thanks that helps.
Out of curiosity, do you know why the 4x4 would be different? What under the ood would make it not work on 2wd? Just wondering if you know.

I just ordered an assembly manual online so I can try to piece this together.

There is an Excel spreadsheet that gives the page numbers for the components that are installed, as the manual doesn't have page numbers. I have it but don't seem to be able to upload it.

Anyone remember where that spreadsheet is located?

Here is a link to the service manuals.
