A few pics for anyone who needs to rebuild their Sparcraft vang. The replacement gas shocks are available from Sparcraft. I got mine from http://www.americanriggingsupply.com/ for a reasonable price and quick service.
First step after taking the vang off the boom was to drill out the rivets at the mast end of the vang. On my vang the mast end was riveted and the boom end was screwed. This is apparently somewhat random on these vangs and you may have all rivets or all screws.
The vang put back together and now the shocks actually hold up the boom. The repair is quick and pretty easy. The longest time was spent drilling and tapping the lower end piece where the rivets were drilled out. I used machine screws instead of rivets to put it back together.
