Wishbone/control arm differences
Hey all,
While dropping my ('89 951)'s engine for a re-seal and all the sundry "while I'm here.."'s, one of the surprises I ran into was mismatched wishbones. One is a 951 (951.341.150.10) p/n, the other a 944 (944.341.149.02). They're pretty much identical beyond an unused boss on the 944 numbered arm. Any reason I shouldn't just clean these up, rebuild em, and put them back?
Looking around I can probably find replacements fairly cheap, but figured I may as well ask here first!

The casting PN changed at some point in production. No issue running a mismatch as long as they're the same offset. The boss was used to hold an air deflector "scoop" for brake cooling on later models.

Can't believe I forgot: pictures. Thanks for the input, guys! I ended up finding a friendly local who offered up some matching spares anyway

Another suggestion is to replace the original caster blocks with the newer 968 caster blocks. As they newer versions have less rubber, they provide better handling. I also believe the original versions of these are no longer available.

The bosses being for a later model makes sense now - looking at the casting marks the left side arm (944 p/n) seems to have been made in 2001! The 951 arm here is an original from 1987.
Edit: this would also explain why the left arm's ball joint is in reasonable condition
