Oh sorry its a 13' so it will fit with out a D&R. And I read through the other thread but all the info I was looking for wasn't there so I decided to post rather than hijack.
Couple things I'm specifically looking for-
1. Anti Stab kit. Whats the purpose, and do I need it? I have never run anything but a stock track.
Anti Stab kit is needed when you run an extrovert driver which has teeth that hook into the open window on the track. This is where your suspension rails are and to get clearance for the extrovert driver, the suspension rail will need to be cut down and then an Antistab kit bolt on where your limiter strap cross bar is. This will keep the trimmed rail tip from hooking a window of the track and ripping it.
2. Are drivers something that I can swap myself or will the shaft need to be sent somewhere like say avid?
If you have a press, you can remove your old drivers and install the new ones. Just measure where the drivers need to be in relation to window on the track. You will need 3.0" pitch 7 tooth drivers(2 of them) for the challenger 3". Here is a link to the drivers: https://www.avid-products.com/store/ProdDet.cfm?ProdID=143
3. What do I have for options clutching wise and what going to be dialed the best for that track? Will I be needing to do a full kit? Or would MDS weights with less weight be sufficient?
I personally prefer MTX weights, but this is with a stock lug height track. Maybe a lower final angle helix may be required, but realize you are effectively gearing the sled down with the 7 tooth drivers. Stock drivers are 8 tooth 2.86" pitch. This will help with the bigger lug track. IMO I would try and see if you maintain your RPM with the stock helix first.
4. The track is 1" longer, i'm assuming that I can just back up the rear wheels and have enough tension? Or are there benefits from going to a 8 or 9" wheels?
