Front suspension upper/lower arm - special tool for aligning pivot and bushings ?

there is excessive wear in the upper arm pivot/bushings on my 1948 super six, and I need to replace them. According to the Hudson manual, I should use tool 1860, which apparently spreads the arm by 1/16 inch to get the alignment correct.  As I am never going to find the correct tool (!!) has anyone improvised a way to get the alignjment correct ?  Any help would be much appreciated.  Thank you.

    A turnbuckle can be made into a quick and dirty spreader. Cut off the hooks or eyes that a turnbuckle typically comes with and weld on something that will engage with the arms.

    Thanks Bob.
    Does anyone know where to measure for the 1/16 inch stretch, is it at the point where the bushings go into the arm ?

    I am in the United Kingdom, hence chances of finding any original tools is zero so I have to improvise !!

    I have now discovered the lower arm bushes and pivots are also worn. The Hudson manual staes thet need to use tool 1052 to maintain certain distances.  Does anyone have a picture of what the tools look like, I am hoping I can make a tool up. 
    Thank you.

    Doc  the following pictures are from the 1954 Kent-Moore Hudson Special tools catalogue.   I have also included a picture  of the J1052 tool that I recently purchased from a eBay vendor.

    I just ground a length of square steel tube to the correct dimension and hammered it into position before  installing the bushings.
