Physical dimensions and such I think they are the same. Wiring plugs may be different. AC amplifier between 60 and 62 is different. I've stripped down a couple of 62s and a few 60s but never set these components side by side to compare.
thanks for all the responses ... I changed from a fj60 dash to a fj62 dash and was wondering if i just need the different duct work to get all the vents attached or if the whole area where it attaches was also different. sounds like the different size duct pieces might work
