Is there a repair for 2nd gear synchro in the 4 speed SM 420 box? I got the repair kit from the company up in the north west area. I don't remember the name. They carry repair parts for all our trans. I believe they said 2nd synchro is no longer available. I went thru the box 2 years ago and its a daily driver. Sure would like to use 2nd and not have to come to a full stop first. Truck is a 54 3600.
Thanks Guys
