Rear axle assembly on a '76 is 54" WMS to WMS, '88-on is 58". If your rear is 4.56 ratio just swap in a later model 4.10 ratio 3rd member & retain the narrower axle assembly. The 2.3 engine/cable clutch MSG-5 tranny from a '90 is the same as a '86-'87, so if you're aware of the problems encountered with a '86-'87 swap the '90 swap will be the same. A '90 2.6 engine/hydraulic clutch MUA-5 tranny swap will be a different story.
