Bushing part #s

[YellowMonster]

My dealer ordered the new bushings today so I'll probably get them replaced sometime next week.
The temperatures have been in the 60-70 degrees here in San Jose, CA... so I don't hear the "clunk" now, but anyway, I wanted them replaced, because I don't want the clunking noise to appear again when it gets colder.

Odd, the part number for my car's bushing replacement is:
BN7H-34-156... so what am I getting if everyone else is receiving the BN7H-28-156C part number? No squeaks though either way... guess I'll just wait and see as time goes by.

Hmm, well- my new bushings are in, but the gentleman who did all of the calling to Mazda, ordered the parts, etc- is out until next week. The parts guy that I talked to did his best though, and this is the info that he was able to provide.
The old Mazda # is: BN7H-28-156B
The new one is: BN7H-28-156C
I am having them put on Tues the 19th, so I will update then if anyone is interested.
The fact that there was not a new number issued indicates that there was an engineering change, and not a supplier issue. Hopefully Rev C does the trick.
