1955-57 Chevy Belair Transmission Side Mount Conversion Kit, TH350, TH400, 700R4

$179

When running old style front motor mounts, a traditional rear trans crossmember applies severe stresses on the bell housing making it vulnerable to cracks and fractures. Our kit eliminates this situation by supporting the transmission further forward and on each side. This kit replaces the original transmission side mounts. 

Kit includes:

  • Transmission Brackets (Powder Coated Black)
  • Frame Brackets (Powder Coated Black)
  • Poly Urethane Bushings
  • Mounting Hardware

Notes:

  • For Turbo 350 and 400 & 700R4

Product fits: 1955 1956 1957 Chevy Belair, 210 150
