I am swapping front ends onmy 1980 FJ40 and have a tech question. Is the front axle out of a 1971 FJ40 the same as i have in the 1980? If so thats great. If not whats the difference? I cut & rolled the knuckles on the housing out of the 1971 and I plan to install the "Rock Ring" knuckle kits but noticed on Iron Pigs website that it states ""Fits 1976-1989 Toyota Land Cruiser FJ40, FJ55, FJ60, FJ62 and Minitruck solid front axle"". I called to speak to tech but did not recieve any help from the front desk.
This brings me to another question. I also purchased the 6-Gun knuckle kit from trail gear and wonder if these too might not fir the 1971 FJ40 housing. I spoke to a tech at TG, he was very willing to help but was not familiar with FJ specs. Any Help woul be greatly appreciated.
