FRANK in the 10's : I got the two square swing arms out to day = # 1 measured 22 1/2" from center of pivot bolt to center of axel. front pivot bolt hole 14mm. , 3 3/4" longer than stock F-ARM, Rear spread 8 3/4" [ which the arm builders on here said is to narrow ] top pivot bracket 9 1/4" wide , w/ slide in 14mm inserts, Square arms are 70.40mm high by 30.35mm wide , has dog bone and shock.
#2 = 21 1/2" from center of axel to center of pivot bolt = this bolt 20mm w/slide in bushings, top pivot bracket 8 5/8 " wide, rear spread 9 3/4" about the same as the F-ARM. Square arms are 70.43mm high and 30.73mm wide. NO AXELS FOR BOTH ARMS = my nephew a few years back took 5 complete arms to make KZ's a single mono shock and he took all the axels, spacers, bolts and nuts. They both have the pivot bolts and hardware.
SEEMS young blood TREY might want a extended arm for his SOHC, could he not pull it off and have TUROB-D do his magic

?
No 7.5" over from a stock F-arm in my outbuilding, sorry.....
