Rear line is 1/4" and front lines are 3/16" on my 83. you should run the line lock after the combination valve on the frame. NHRA requires the line lock to be after combo valve. front lines are 3/16"

Same size on my '78.

Ok cool, thanks guys. Looks like I will need some adaptors from 3/16 to 1/8 for my tci linelock.
