128" ripsaw on apex

[GT man]

I am seriously thinking about adding the four inch rail extenders to my apex and installing a 128" ripsaw track. The supplier said that he's sure that the tunnel doesn't need to be extended. What do you guys think. I still don't have my sled so I can't check out the clearance when the rear suspension when it is fully depressed. I also was wondering what my stock ripsaw track would be worth to sell.

Looks to me like it would fit. I see them selling around here for about $350.

The flap gets sucked in horribly with the 121", way too close with 128.

Are you talking about a 128X15 or 128x13.5?
