hi everyone im a rookie when it comes to chinook , but i need some suggestions,,if i buy a chinook camper for 1976 or 79 what would anyone recommend to convert it to a 4x4 cab , like to know what would be the easiest or perfect fit for the camper. especially installing the camper to the cab which toyota year would have the same fittings,,also i notice some use a 1980 toyota , but the horsepower not too strong how would a 1986 toyota fit, can anyone advise me before i invest my money thank you.
