Help on measurment for lower a-arms/dropped arms?Spring Dia.? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I bought some DJM upper and lower a-arms for my 1970 c-10 used they were modded by p.o. he cut the part on lower arms that sat inside spring to keep it in place. So does anyone know the inside dia. of the spring? Or the size this should be? Reason I ask and dont measure is I have a buddy doing the reinstal of missing peice and dont have my springs out to measure. Thanks for any and all help.
