Cast Control Arm ?

[Richard Hoffman]

Hey all, I have a question on the cast control arms for typ89.  I snagged a
pair at a junkyard today for $11.50.  Naturally the control arm bushings are
shot.
I already have new bushings for the stamped arms (8A0 407 181).  Does anyone
know if these can be used on the cast control arms?
If not, does anyone out there want to trade 4 stamped-style for 4 cast-style
bushings?  Hey can't blame a guy for trying, right? :)
Thanks for your help!
