Longer U bolts

[Hair]

I have coils in back and I want to add a 1.5" lowering blocks. I need some longer U-bolts. What/Where's the easiest way/place to get some? I don't have no spring company next door that I can go to and say "Oh, will you make me a custom set right quick for $12.80." So what do you guys do without paying $50 or $60 for a stupid kit with 2 U-bolts and a block of steel? Do they have longer ones for a different year model or type that I could pick up at the parts store maybe? What do you do? I could bend a bar of allthread and make them, but I don't like that idea. What is the easiest/best thing to do?
