Thanks Dave, I'll postpone installing the servo till the end of the build and hope I'll find i in another bag. Buying standard hardware is not easy around here.
If you don't find it in one of the other bags I have a few solutions to help you get out on track.
1 Check with your local shop if they can get the replacement sent to you from TLR.
2 If your local shop carries TLR they might have either a 5-40x7/8 screw you could cut the head off. Or if they stock TLR 1/8 parts you could use LOSA6045 which is the same size steering link and set screw from the 8ight series of vehicles.
3 I just checked and you could find a 3x22 set screw or cut down a 3mm bolt to 22mm long. I just tried installing a 3x8 screw into a new tie rod and could not pull it out with pliers so you should be fine using a 3mm screw. I would use some tire glue on the 3mm screw when you thread it into the tie rod.
Have fun with your new truck!
