Couple of Qestions

[ProStreet68SB]

Wondering where people are getting the u-bolts that hold the rear end to the trailing arms. Also, what kind of bushings are people using on the trailing arms.

Also have a question about headers, I've been looking on Summit, and they seem to have a good deal on Tri-Y's but it says their for K30s with a big block. But I'm wondering will they work on a c10 with a big block in it?

Thanks,

P.S. here is a link to the headers I was looking at.
