Couldnt tell you what thread the stock ones are but the bolts are 13mm head on the stocks.

There are 28 bolts, 10 10mm , 16 13mm and 2 13mm with big washer that goes up front. I could find dimensions and thread pitch this weeked

Btw 8 13mm bolts that bolts on the bottom, dont screw them straight up, they have to be angle out. You will see

Here are those bolts you gonna need

8 x M8-1.25 x 30mm with 24mm washer
10 x M6-1.00 x 17mm with 24mm washer
8 x M12- 1.50 stud with M6-1.00 inner threads (these may come w/running boards
2 x M8-1.25 x 50mm with 31.5mm washer

Make sure you get stainless steel or good grade bolts/washers because they will tend to rust
