How much drop on the crossbar and how big is the loop? Will it fit with a 3.5" driveshaft?

 

Drop on the crossbar? I guess you mean how much further does it stick down in the middle... About an inch lower I suppose, depending on if you have to space it any for proper driveshaft clearance (I had to space mine down a bit). I run mine with an LS1 shaft. Arent they 3.5, or are they 3 inch Anyway, I just ran my rear suspension through it's travel to make sure the DS would clear at the high and low points.

 

Thanks for the reply. I think the LS1 ds is around 3 inches. How much clearance would you say the loop has on the sides?
