Hey guys, i am converting my RX1 121'' to a 151'' from a 05 RX moutain, i looked everywhere and cant find what i am looking for, i would like to find the measurement from the '' driveshaft'' to the cross tube where the front mounting bolt goes in and from the tunnel top to that same tube. Also some measurement for the back. Any other advice would be appreciated. If anyone did this before picture would even be better !!!
 
On an Apex Mtn the distance between the axle and the front mount is 12".

I am putting an timbersled skid in my 03RX now. I am using rails from an 05 RX1M. I found 10" to be just right.

Not sure if this would be the same as a stock suspension. Hope it helps
 
I have done this mod before. Simply purchase the front, mid, and rear mounts for an RX-1 Mtn. The holes are already there in the tunnel for you to rivet and bolt the mounts in. If you're going with a 1.5" or larger track I'd drop down to an 8T set of drivers. I kept my 9T but had to remove the tunnel protectors. Don't worry about clutching changes, however if you keep the 9T drivers I'd switch to a 22T upper gear and a 68L chain. Hartman makes a good tunnel extension that makes the sled look so much better. Just beware, the sled is over 10 feet long when finished and you need to fold up the rear bumper to fit it in a 10 foot enclosed trailer.
