Fitting 105 parts to an 80- what fits?

[artech]

Does anyone know if the fuel fill from a 105 will fit on an 80 series truck? Just trying to plan out a sub tank install and the 105's are cheaper. Any other parts compatibility between the two models?

105 steering box sector shaft is the most common upgrade

105 sector shaft and pitman arm would be a nice upgrade for the 80s as well.

Loosely, suspension and running gear will cross over. But not everything.

Almost nothing from body, interior, electrical will be interchangeable
