I have a complete set up with brackets that I removed from a 1964 98, I believe it will fit your 62. I will check out my 61 and see if it will just boltup.
The only real difference in the 61, 62 and 64 are the exhaust manifolds on the 64 are different than the other two. All of the heads interchange and the brackets bolt to the pass side head and the block. I will get some pics of my installation ( with generator) and some of the stuff I have. I'll try to determine if it will work for you. I will need your e mail to send the pic's.
I have the whole system if you are interested. You will also need the pass side inner fender well, it has a removable panel to service the A/C. I don't know if the 64 is the same as the 62 but I'll also check that out for you.
Thanx, Dave
