hi all i have an 89 sierra sapphire cosworth with rusty chassis legs and have found an 84 3dr sierra cosworth rep for sale that is suppost to have a solid chassis and no rust, i am wondering if my engine, gearbox and ancellieries will just bolt in and be an easy conversion or will there be any problems? thanks all!!

Fuse box and that area of the bulhead is differnt on 3dr/Sapphire so not a straight swap.
Interior is all entirely different.
Chassis legs are different lengths.

Check the gearbox tunnel in the base model will accept a t5 box some of the very early models had a smaller gearbox tunnel but I think that was the 1.3 pinto versions as I've only heard of a very rare few that couldn't fit the t5 gearbox, you will also need to drill holes for the cosworth gearbox mount and add some strengthening plates as the gearbox tunnel/floor is very thin metal to hold the weight of the gearbox whereAs the cosworth she'll already has the mounting points and spacer skin on the underside where it bolts up
