I've noticed a few people have mentioned changing their 3.6 CWP for a 3.9 CWP on a 7.5" diff. Man on here done the swap and if so what did you like/dislike about the change?

Also, for those still on the standard speedo cable drive, did you bother having it recalibrated etc and if so where did you get it done?

Also, is it possible to buy the 3.9CWP new still?

Cheers for any experiences
