Yes, the interiors and panels are MOSTLY the same between a 185 and a 184. However the following things WONT fit (that I know of) LHS Front Seat RHS Front Seat Interior Carpet The ST185 has a different floorpan to the 184, and if you were trying to find a stripped one you would need to make sure it still had its drive train. Also, making a 5SGTE is not as easy as just slapping together a 5SFE and a 3SGTE. both trentmeyer23 and myself have done extensive research, and built 5SGTEs. Agreed, granted mechanical experience will help, but you will need to do a hell of a lot of research along the way. It is MUCH more complicated if you do things the right way.
