You're totally right. The 80 is really different from the 105. I would have thought the 80-105 similarity in wheelbase, track width, and axle housings would basically guarantee similar frame. But clearly not. Seems everything mounts further out. Even shock towers!The sane diagrams are available for 80series.
Body mount positions are slightly different
In your opinion, was there any aspect (besides engine choice) on the 80 that was superior over the 105?The 80 and 105 frame and suspension, steering, wheel base, track, running gear etc is essentially the same. The 105 is basically an upgrade on the 80. Configuration is essentially the same.
There is differences due to enhanced engineering, manufacturing efficiency etc.
The 105 body is wider, heavier and stronger. Every panel is different to the 80. Its a completely new body shell
I've had both. The 105 has better NVH, more room internally, better seating, more modern dash design and instrumentation.
105 and 100 series were built with inline 6 diesels and 1fz-fe. 80 series and 105 engines and running gear will be bolt in interchangeable.
100 series maybe less so of you're using a 2uz V8
The 100 series frame was altered to allow for V8 engine, and IFS
A lot of accessories aren't interchangeable due to differences with the frame.
