You need the rear backing plates from a 924S. They are steel and basically replace the drum backing plate. You re-use the bearing retainer from the VW setup. It is recommened that you drill a hole in the 924S backingplate to give the oil a place to drain (like the drum backingplate has). Then you can use either 924S or early (83-85) 944 rear hubs. If you have short axle, chop 16mm off the front of the Porsche hub. Use all the early 944/924S ebrake parts and add rotor/caliper and you're done!

Or, talk to MBT. They make the backingplate specifically for swingaxle cars.

flat/lanner thank you very much for the info. but now im kinda confused, i called a vw shop a few days ago, i told them i found a NA 86 944 and i was taking the rear brakes off, they told me to send them the backing plates and hubs to get some machine work done and they would bolt on...... any idea what they need to machine? im jus trying to find the simplest way to do this without having to find 2 different cars to get brake parts from. oh and who is MTB?
thanks for the help
this is actually for a 65 bus with a 67 bug swing axle trany (long axle. short spline)

IF you can get your hands on a 924S, then you have all the parts required for a NA conversion.

The 86 arms may or may not the the aluminum ones. I think the 944's switched from steel to alum rear arms in early 86.

Here are pics of the elusive 924 part. It's from a 924, with the 5-bolt brake option (standard 924's were 4 bolt drums in the back). It is NOT from the 924S (which has aluminum trailing arms) They are getting hard to find, so MBT may be the only option. Anybody know how much the MBT pieces are?

MbT steel backing plates

Yeah ,
When I got a hold of Uwe he quoted me 450euro for a refurbished pair sandblasted and electroplated. No mention of new ones. Although it sure looks like they make em.
Looks good! But spendy!

there has to be another way thats easyer, this shop told me to get the complete set of rear brakes off a 84ish 944 and they would machine them to fit for like 150 bucks. does any one know this method?

Not too sure about this method. You could use a 944 aluminum backing plate, and you will need a spacer to capture the bearing properly, BUT then you only have a oil seal to rely on to prevent oil from leaking. By using the 924 ones, you use the stock beetle bearing caps and you have a oil seal AND slinger to prevent oil leaks. I'll try to see if it's possible to machine a 944 aluminum one for a swingaxle setup....
