Guilty as charged. FYI, my website,
www.hiperformanceautoservice.com, should show just about all of the parts you will need.
I forgot to mention in my previous post about the need for a rear brake drum puller so you can remove the drums safely without damaging them as the drums are expensive.
Of course there is a special tool and my brother, hiperfauto here on Turbobricks and his former partner found the original Volvo tool lacking in longevity and they made their own drum puller which is the one we use still use to this day over 30 years later.
He still makes them so I have a rental tool or you buy 1 out right. The rental fee is $20.00 a month plus shipping or $140.00 plus shipping if you want to buy 1.
There are other drum pullers, but I strongly suggest what ever you use bolts to all 5 wheel studs as opposed to a puller that grabs the outside of the drum. The latter puller usually bends the drum long before it budges it off the tapered axle shaft.
And in case you didn't know, just about all the hardware on your Volvo is either UNC or UNF threads using standard, not metric wrenches, but there are exceptions. For example, all of the female brake/clutch line fittings need metric wrenches even though they have 3/8" x 24 threads. The same is true of the original flex brake and clutch hoses as well as the fittings for the brake and clutch master cylinders, but IIRC, some of the clutch hydraulic lines have 7/16" threads.
Let me know if you need some more info and when you are ready to order parts.
