14. Floor Brace

The floor brace cannot simply be bolted back into place. The T5 is 3 inches longer than the TH200‑4R and consequently places the front universal joint coincident with the floor brace. The floor brace must be set back 3 inches and shimmed away from the floor by fabricating a spacer for each side of the brace. Alternatively, an NHRA accepted driveshaft loop, fabricated specifically for use in a 1978‑1988 GM A/G body with a T5 or TH700‑R4, can be purchased from James Happe (Figure 14‑1).
