of upper and lower arms cut to lay out..............not sure exactly how to pie cut i think i got it but would like to see some "in progress pics"....and how much i have to notch the lowers ...thanks
u shouldn't have 2 cut ur arms like that 2 lay out,i lay out the front with 20's,check my pic with the motor compartment,i'll try & find some better pics 2 show what i've done!
