jubilee bracelet & endlinks question

[sleedawg]

So, I got the used 62510H jubilee bracelet with 555 endlinks in the mail today. I'm a little concerned now. Aren't the end links interchangeable on a jubilee? I needed a 62510H with 502B endlink and thought I could just swap out the endlinks. The spring bars don't seem to want to come out. (looks integral to the bracelet) I just can't imagine that the spring bars aren't replaceable. I know nothing about these old jubilees, so I'm hoping that maybe that's how the older jubilees were constructed. But, I wouldn't think Rolex would be that stupid to not make these bracelets serviceable. I'll be stopping by the RSC in the morning and will have it looked at. In regards to the seller, he's a well respect watch and watch parts seller with lots of experience with Rolex. I'm giving him the benefit of the doubt until Rolex tells me it's non-authentic. Love to hear the expert opinions.
