Thanks for the $aving tip. Went to local hardware store, told the guy what I was doin and he pushed me away from stainless. He said it was softer than reg. steel and gave me some grade 8 hex bolts. I used 1 1/8" bronze sleeves for spacers and it worked out sweet. When I took out the HD 1" bolts GRD8 was stamped on them. I probably will only do the right side because the air cleaner was what was pushing my leg out any way. 
I noticed the GRD 8 on the OEM bolts as well. My thoughts were two:
Even at 300 lbs, I am not going to bend two 1/2" Stainless bolts by standing up on the floorboards so GRD8 may be overkill. Secondly, on the left floorboard there is only one GRD8 x 1/2" bolt and two GRD3 standard bolts x 5/16 dia. holding the floorboard to the frame and jiffy stand.
So on the left side we need two spacers with clearance for a 5/16" bolt and one spacer for a 1/2" bolt.
If you are using spacers that are 2" long, you will need two 5/16 N.C bolts x 3" long and one 1/2" N.C bolt 3" long.
Also the 1/2" bolt on the left side must have an Allen Head, there is no way to get a socket or wrench on a hex head capscrew bolt on the left side. (Hex head capscrews are fine on the right side though)
