Im about to try to install my shackles for a third time..Im just gonna impact hammer the bolts right out.. I plan to replace them with new ones. Does anyone know off hand the size of the grade 8 bolts I need to get so I can have them before immobilizing my blazer.. Thanks for the help very much appreciated...

 

i dont off hand but if its any help. i know your truck is going to be down but if you can get a ride you can bring the cut bolts into the hardware store and get them matched up. im lucky enough to have 2 spring shops within 10 miles of my house so you can usually go in there and say i need rear spring bolts for a 03 s10 and they have all the sizes on files

 

14mm but some people are replacing them with 9/16". You can measure length easily.
