I went out to the warehouse and measured the frame clamps on a Swagman roof mount bike rack, # S64720. The maximum the jaws will open, at the narrowest point, is 2-1/8 inches. The maximum at the center of the jaws where they are the furthest apart is 3 inches. This is with at least 3 full turns of the knob on the bolt. I made a picture that shows the measurements for you. view full answer...
Yes, your 1998 Chevy Tracker with a manual transmission can be flat towed. You will need the following parts tow bar, safety cables, base plate kit, wiring harness, supplemental braking system, and potentially a high low adapter.
I have listed everything you will need below along with any installation videos we may have. There are two different options for base plate kits depending on whether or not your Tracker has two or four doors and you will also need an adapter.
