Hi All. I'm thinking about converting the rear axle in my 66 P220 to one from a later model (either 1800E/ES or 240, and yes, I know it's not a bolt-on operation - requires welding new brackets onto the axle tube - anyone who has done this I'd be interested to hear about it), which would result in having the later (5x108mm) wheel stud/hub pattern. What's the best way to change over the front? Is it possible to directly bolt the front hubs/knuckles/brakes from an 1800E/ES onto the front of my P220? I'm also planning to convert to the dual diagonal brake circuits. Swapping front hardware from an 1800E/ES would go a long ways towards helping in this respect. Are there other options for the front swap? Will 140 or 164 front hardware (knuckle/hub/brake) work at all, or is it totally different.

Thanks!

you know i'm interested in doing the same thing this winter but i was thinking of stripping my buddie's 142 for the brake parts. sure would like to hear from anyone who's tried putting a different drive train in their wagon.

Fronts look pretty straight forward. Calipers, brackets, and front wheel bearings are the same part number for single circuit Amazons and P1800s. l bet that the replacing the discs will get you there.

If your goal is 5 on 108 all around, the easiest way is probably to redrill the rear drums to 5 on 108. I believe the P1800s with drums were always 5 on 4.5". If you want discs that is another story.

CVI sells a adapter kit to install an early Amazon sedan axle into the 220 for 1295 kr. My guess is that with a little research this may enable you to put a 66-70 p1800 rear axle into an Amazon.

Comparing the 66-70 rear axle parts for 1800s and Amazons in the CVI catalogs, I see a lot of common parts like rear brake shoes. Don't hold me to this, but, once the sedan axle is in the car everything else related to disc brakes will be a bolt up with the exception of emergency brake cables. It's a bit of a crap shoot, but If you can find brake and axle parts you need, take measurements and compare.

But what aboutyhe axle anyway??

Surely someone out there has tried bolting the brake parts up? I have seen a lot of dancing about the subject. Mostly though, about the 1800 rear axle not fitting the 220 suspension. What about installing 1800 brackets, backing plates, calipers, and discs on the existing 220 axle housing? Specifically what is the bolt pattern on the axle housing outer flange. That is the key in my mind!

Volvo has a long held reputation for re-utilizing parts in a number of applications. Is this possibly one of them? That is my two cents!! Comments
