measure the back of your engine to see if you have clearance to your new swingarm, then measure the frame internal space and compare to the swing arm width.
you'll be able to need some washers to clear the gap, or you can get someone to build new teflon/poly bushings to clear the gap if they don't match perfectly.
otherewise, why don't you try ebay for a used swingarm or keepitroostin.com? it will make the job easier and it's not that expensive.
