this forum looks like a good shot at helping me i.d. a IFS on a street rod I just got. it is u/l control arms-look like a cast steel,not stamped. torsion bar ,shocks located & attached to front of lower a-arm,spindles almost staight up & down, ball joints top & bottom,disc brakes are datsun(i believe)with pistons on both sides of caliper.solid rotor.has rack & pinion steering(rear steer) that looks like it is right for susp setup. the a-arms have a pretty wide spacing on them between the attaching bolts. this setup looks to me like 70's,1980 vintage. brake master cylinder setup is also datsun. I thought maybe datsun truck-- i f anyone has a hint please advise. I can get measurements or try to give better describtion if I know what/where to look for. previous owner does not/will not tellme ,got car thru 2nd party, both where major dicks.TIA
