    2X3 on mine as well althou I think SFI will accept 2X2 in a 25.5 standard?; to be sure check with one of the chassis guys but I think thats right.

    I post pics tonight... can't get to photobucket here.


    I think where most of you have your problems with all of this, is the fact that you really don't fully understand the internal workings and dynamics of the common combustion engine. There is no magic tune up, and motors are stupid. The only time a motor will complain is when something is wrong.

    The 2x3 will slide into the rear frame rails and be snug, thats why i used the
    2x3. I slid them in maybe 2' into the rear frame.
