How to install bigger wastegate puck???

[Roc87]

I have a used ported elbow here for my Iroc, and I also have a larger puck. I'm not sure if the elbow has a larger than stock puck or not, but the larger puck I have is bigger than the puck in the elbow. If it turns out to be the stock puck in the ported elbow, how do I put in the bigger one?
Swapping my alky and PT51 from the GN to the Iroc this weekend, so any suggestions about the puck is greatly appreciated!!

As much as the puck likes to spin on the swing arm, I believe the stocker has to be cut off. The larger puck then needs to be welded on and machined. Not a work bench project as it was explained to me.

Yep... just like Dean said! Grind off the old puck's weld to remove it, get a small, similar sized washer (I used stainless) that just slips over the end of the new puck and weld it in place. Make sure it can move freely when installed, but not so loose that it can flop all over. Hard, to explain, so make sure you take a good look and get a feel for the amount of play the stocker has before you grind it off.

Thanks guys! I'm sure hoping that the puck is bigger than stock now!
