My thoughts are that it depends on who made the torque wrench..... I wouldn't use any of the Harbor Fright crap or some other cheap brand. Go with a good reputable brand such as Snap-On, Mac or older Craftsman USA made wrenches. If your 3/8" wrench is the kind that has a "click" feel when you hit the mark, it would be hard to feel that click since it's on the bottom end of the wrench's range where the click is weak but I still use it if it's a GOOD wrench since it is in range. More important is to be consistent bolt to bolt and go over the bolts again after tighten them all the first time.
A good torque wrench is a considerable investment for two bolts...... Perhaps you can rent one or borrow one.... Some automotive stores will accompany you.
