I need to find a track , tunnel and rail extensions.

Find a track first... maybe on Ebay.

That's an Edge chassis isn't it? You can get a tunnel ext and rail ext kit from SLP.

Pretty easy change really.

I've got an Indy Lite that I did that to last month. Picked up a 136x1.25 from a newer 550 RMK for $85 off CL. The tunnel and rail extensions I had from previous sleds.

Not too hard to do once you get the parts lined up. Hoping to try it out on Saturday to see how well it goes.

You might want to check out the rail extensions at tracks usa. A friend of mine has them on his 02 XC 700 and they are pretty solid.

For small sled you can do easy rail extensions like on the older style phazers / enticers ... simple piece of 3/8" aluminium bolted on each rail and slotted at the back to hod the axel ... find a a track first then a couple of pieces of aluminum flat plate.

finally tearing into the sled
the drive shaft had lost the bearings on the spedo side and never new it
so that adds a bit to the job, but the perfect time to get it fixed
need to drop to smaller drivers
will be going through the clutches , carbs , top end etc making sure all is good for this coming season
have the track 136x1.75
need to get the extensions for rails and tunnel
