Beetle IRS trailing arms - are there different types???
 

A friend of mine has run into problems on his buggy project and it's got both me and him both stumped.

Is it possible to get trailing arms for a type one that are different?
I have just replaced some (long story).

I noticed that one of the arms had much thicker metal for the shock mount. When I fitted all the bearings, spacers etc (from the original ones) one of the disk calipers is approx 1mm too close to the disk. I took it apart to check and evertything is the same both sides (spacers, bearings etc).

Could the trailing arms have different positions for the bearings?
(all bearings are fully home - the disk is too far in towards the middle of the car):confused:

I was looking at an officila vw picture of an early ('68) IRS semi - auto beetle & noticed the trailing arms looked different to the later 1303 arms. Main difference was how the shocks mounted I think. Does anyone know if this was the case?

Hi

Im pretty sure that there is no difference as far as bearings go but, upto 71s used twin spring plates and the later cars used a single spring plate so the traling arm is different.

I just remembered, the early traoiling arms had a thread tapped into them for one hole and the later ones used all through bolts.
