I'm looking for the size of the 2 bolts that are in behind the blinkers holding bumper support. I need to buy replacements. The bolts are shown as "bumper mounting bolts" on the left middle section of the photo attached.

 

88-89 have the typical 10mm bolts there; while 90-91 have 12mm. I think they would be a M8-1.25 if you're looking in the bolt bin of your local hardware store.

 

M8-1.25 was it thank you
