I received my brace, now just need to buy hardware.

It reads this: "Customers have used on 4x4's as well as W350 by using longer bolts. One customer sent the following information: "I bought your steering box brace for my daughters 93 w350, not knowing it was for 2wd applications....I had it, so I figured I'd try modifying it... I got longer bolts obviously, bolting through the factory box plate, the rail, and your bracket... amazing difference in bumpsteer"!

Anyone know how much longer I need the bolts to be? Want to have the right hardware on hand. Truck is at mechanics shop and I can't take measurements. Instructions for 2wd state I need this:

4 - 7/16"- 14 x 1 3/4" Grade "8" bolts
6 - 7/16" Grade "8" Lock Washers
6 - 7/16" Grade "8" Flat Washers
2 - 7/16" Grade "8" Nuts,

Thanks. Larry
