Bought a new Sonnax 1.58 glide planetary thru GNRC which gives a discount to YB members. Order was placed, processed and delivered quicker than quoted, a whole day early!! I was very impressed with the kit and now have a billet reverse servo and 7 clutch/8 steel reverse to go with the 10 clutch drum and super band that was installed the last time I upgraded the trans. The reverse setup could be run with less in the clutch stack to fit whatever your current configuration is but I elected to machine down the lip on the servo to achieve the proper clearance for the 7/8 stack which is working great. The 1.58 has definitely calmed this crazy bitch down and I can now get it off the starting line with way more power and hopefully lower ET's once I get a little more feel for what it will hold. Again thank you Tom and if anyone else needs one of these units I would call Tom and he will fix you up.
