i am going to start making sliders this weekend and i was wondering what size bolts would be the safest to use to bolt it to the frame rail without interfering with my fuel n brake lines on my driver side

 

Grade 8 with some big *** washers

 

If you are going all the way through the frame I suggest sleeving the frame and using grade 8's or higher. Or you can do like most ppl and use self tapping bolts. I think most ppl use 3/8 or 1/2 self tappers. Or you can do like Ido and weld them to the frame.

 

will the self tappers work ive used them on other things and they always seem to back themselves out

 

He's talking about Self tapping bolts, not screws.

Like this

 

what stores carry them. if im not able to find them anywhere is there a way to run a bolt right through the frame rail without disturbing the lines on the frame rail

 

one down fall on that is if the bolts are on to tite there going to start pinching the frame and bend it in not much but enough to bug me that's why mine are just welded on there {{{{see the link i just redid a side also}}}} https://www.cherokeeforum.com/f58/xj...ocation-47869/
hope some of the picture can help you out with it good luck

 

I think i am going to use the self tapping bolts first. If they don't hold up well enough I will weld them on. The only problem is that i have no idea what stores sell them I have spent the past hour searching online. So if anyone has any input on where i can buy them it would help alot.
