bodystyles

spastk — 2009-05-13T19:31:39+00:00

Hardtop (2 and 4 door) Sedan Same floor pan, drivetrain and supension as hardtop. Most of the rest of the body is different however, with head lights, tail lights, interior, bootlids, doors, glass not being interchangeable. Hardtop and sedan front ends are interchangable however, if you take everything off front in front of the windscreen/doors. The only modifications required are to accomodate the different window wipers if you are going from a coupe (1 wiper) to a 4 door (2 wipers).

Finding your chassis code The chassis code is stamped into a thin aluminum (?) plate screwed to the upper firewall in the engine bay. What each part means Typical HB chassis code: E-HBES-200245 Consists of: * E- = fuel type * H = H chassis type (large GT) * B = chassis revision * ES = engine/drivetrain combination * -200245 = production number (not sure of the correct name?)
