According to my plans the four front (forward side of spar) (rear spar wafs) have a bend at .62 from the center of the last hole on the side of the waf closest to the end of the spar, then .38 from that bend point to the center of the wing bolt up hole. The rear side of the spars fittings are .62 and .44 respectively so the 4 back side of rear spar wafs have an extra .06 further from the bend point dimension. So depending on which one of the dimensions you used to make your 8 rear spar wafs Mike, you should only need four wafs instead of 8. Larry H.
