Can a popped seam be restiched?

[RSSSFanatic]

My 69 convertible has the original black comfortweave interior, and it is generally pretty presentable.  However, I have a couple of seams popping on the top corner of the passenger seat and on one seam of the rear seatback.  The vinyl is not torn and is still soft and supple.  It appears that the threads simply disintegrated from the California sun.  Would it be possible to stitch these seams back together?  The one on the top of the rear seat is the most obvious and the one I would like to get fixed the most.  I figure the seat cover could be pulled off and I might be able to get back to the back side to sew it back together by hand.  Has anyone attempted this?  Any suggestions on thread, needles, where to get hog rings, etc.?

Thanks in advance.

Yes, it can be re-stitched (although I'd suggest using the same holes rather than 'restitching'.   Take it to an upholsterer...
