Lifting 406 cab and need longer bolts...

So, I picked up a larger set of tires last weekend and need to lift the raise the cab of my 406. I ran over to Fastenal today and the would have to make the rear cab bolts at a cost of $55 a piece!!!

Just checked McMaster Carr and they don't stock what I need either.

Looking for M14 x 1.5 pitch at 140mm or 165mm. Any ideas? Think MB has longer versions of these bolts?

Thanks for any help!
