suspension linkage geometry problem

[carter of mars]

im trying to put in a vfr single sided swing arm in the 90 model gsxr7 frame and keep the original suspension mounting point. im using a R6 shock cause it was the shortest one i could get, but now i have to make up the bottom linkages. ive tried to use some others off hondas and even the original but none of them fit. ive dodged up some to get the bike to sit but its way to hard.
does anyone know how to go about working out the geometry to make them from scratch?

Have someone like Crazy Tony move the mount for you is the best option I can think of. I've got the remains of a scrap RGV frame you can nick donor material out of.

i moved the mount, well i just made up a new bracket. but still have the linkage problem. might have to check out that rgv linkage though.
ive got rough dimensions just had to get them exact.
