Installation of your Tin Man Subframe Connectors
Step 1) Make sure the car is sitting level and not twisted so that it is in a natural state when the sub frame connectors are installed.
Step 2) Cut open the end of the front sub frame by grinding off the corners or by using a cut off tool. (See diagram)
Step 3) Drill two ½” holes in each side of both front sub frames starting from the back and measuring forward 2” and 4”. (See diagram)
Step 4) Slide the sub frame connector into the end of the front Subframe about 6” so that the middle bend follows the contour of the floor. Mark around the rear of the sub frame connector on the rear sub frame to determine areas to be cleaned up for welding.
Step 5) Remove subframe connector and grind all areas that will be welded (around holes, around end of front sub and around the area that you marked on the rear sub).
Step 6) Re-install the connector and align. Tack rear of the connector in place. Verify that it is where you want it.
Step 7) Plug weld thru the drilled holes to connect the front sub to the connector. Bend end of front sub to close up the gap between the sub and the connector and weld.
Step 8) Weld around the rear of the connector to tie it to the rear sub
Step 9) Repeat to the other side making sure that they are in the same location.
