Which rear shackles to use?

[Denee007]

Hi! I didn't realize there were two different styles of rear shackles until now. Is one better than the other? The original style is quite a bit more money, like 35.oo vs. 75.oo for one side. Which would you buy?

Obviously this is like the original: I like original looking parts.





Something turns me off regarding one bolt holding the shackle together.






THis is this entire kit~ I think it was Ecklers, about 135.oo. But if this kit would do the job and my rear axle shackles won't fall apart with this~ that'd be OK too!
