The frame perches from any truck with a 460 up to 1979 will bolt right in after you grind the old rivets off. Then you can use the factory mounts. Donor truck would be your best bet, rob what you need, sell some more and shred the rest, You'll probably make money.

Ford did not offer the 460 with 4WD until 1983 (F350's only). These mounts will not work on anything prior to 1980.
4WD's do not have an engine crossmember. The perches bolt to the frame rails.

The factory 2WD 460 perches will not bolt in to the earlier 4x4 frames; they are significantly different. Your '66 4x4 is actually a '64 type frame and cab with '66 trim.
There are after-market motor mounts made to put a 460 in pre-'65 trucks, but several that I know of who have used them in 4x2 trucks regretted it. They are not strong enough to handle the 460 torque to the point that one user nearly had a 460 fan blade for a hood ornament.

These may work as the frames are the same width. Backing frame plates and new holes will need to be drilled. All this will need to be worked out as custom as the 66 frame is the first year of the coil spring front axle.

I just picked up a 76 F250 4x4 with what the PO said was a 79 429 engine, but sense Ford did not make a 429 after 73, I will have yet to figure it out, most likey a 460. It looks like they used the original trans and transfer case with a 460 bellhousing. I have to go over this next weekend to do some work on it, I will look at the mounts and see if I can tell what was done. Truck is about 160 miles from me.

These trucks use the same cab as 1965/66 F100/250 2WD's. The radiator support is the same as 1965 F100/250 2WD's.
1966 was the first year F100 4WD's had coil spring front suspension.
But you cannot use 2WD perches on this truck or any other 1959/79 4WD. There's no engine crossmember to bolt them to.
4WD perches bolt to the frame rails.

Aw shucks. I sure thought the '66 4wd was the same as '64 cabs.
Waaaeeelll, I reckon I got the why it won't work wrong - even if I got the answer right.
Although I am glad you corrected it, Bill!

There are other mounts out there but the L&L are the stoutest. You will need to basically throw away and cut out all the stock stuff and custom mount it. Also your case is mated for 1966 and may or may not need different trans mount.
Before you buy it look to the VIN if it is a true factory 4x4 it will have a F11 as the first three digits of the VIN.

You can do a search in the '70s dentside section of FTE for 460 swaps.
There are posts on modifying the fe perches to match the 460 and redrilling the existing fe mounts to fit the 460.
You can use perches from a '70s 351m-400 4x4 and mounts from L&L. Or, you can drill the holes on fe mounts to fit.
One of many:

You will probably want the crossmember out of a '70s truck too.
You will need a rear sump pan and pickup if not on the present motor to clear the differential.
