[The Newell]

Yes, cracking is normal, and I agree with Ken its always a concern for alarm. Some of mine on my 76 were good. some were starting to crack and one was brand new. The cracked ones I would opt to replace. Ask yourself do you want to replace your airbags in the comfort of your shop or at your convenience etc. Or replace it on a rainy day on the side of the road? If you ask me I say replace them.
