Info on a 944 arm swap

[jrinlv]

Dose anyone know what size bolt goes in through the alum arm to bolt it to the pan?

I also set every thing in place and it dose not seem like the stock VW spring plates will be the right lenght to work with my late 944 arms. Nothing is bolted into place (note question one) just eyeballing it, thanks for any info JR

JR,

Those bolts are 14x1.5 and 80 mm long.

I just used the stock beetle IRS pivot bolts after swapping the aluminum trailing arm's rubber bushings for some urethane units made for the beetle. These bushings have a larger inner bore than the Porsche units due to the beefy shoulder on the beetle pivot bolt.

With the aluminum trailing arms you will need to use the Porsche spring plates due to differences in the bolt pattern where they attach to the trailing arm.

The rubber bushings are bonded on to the Porsche spring plates. If you cut/grind/burn them off you can use rubber or urethane spring plate grommets and the spring plate retainer for a beetle. I ended up using the inner urethane bushing for a beetle, an aftermarket hard plastic outer bushing for the 944, and cut-down aluminum 944 spring plate retainers.

-Mark.

Thanks for the info, I never had the stock IRS bolts, I bought the pan bear. I thought that the stock spring plates were what you used, back to the internet to find more parts. but thanks again for the info..JR

JR,

Those pivot bolts and the washers that go with them are hard to find but Aircooled.net has new ones.

Cool thanks,

hows the snow?

[Bugnutz]

Snow's not so bad here, but fifty miles East is another story- Oswego NY was on the national news for ten feet of snow a couple of weeks back, maybe you saw it.

wrenchnride do those rotors center on the hubs, or do they just fit over the studs?

RCH they just fit over the studs (pretty tight). This is all stock '87 944T parts.

[RCH]

okay, I was looking at these 87 951 trailing arms I have here, wasnt sure how the rotor fits up. Now to find some rotors and big calipers!

Will any yr spring plates do or should I stay with the late ones, I have a line on some from a 86 at a good deal...Thanks JR

[jrinlv]

Also will the stock VW torsion bar work or should I pick one up too? JR

You can use the stock torsion bars (they are just softer ride) They both share the same spline pattern...

Not sure '86 will work on that one. If you get '87 later trailing arms, use the late spring plates just to be safe...
