Hello!
My son and I are re-working a 66 f-100. It currently has original hydraulic brakes (not power)2wd and has manual steering with a 4 speed trans. I have purchased a 1973 2wd Ranger F-100 to be a donor for the brakes (disk and power) as well as the power steering. Eventually the 390 and C6 too. Can anyone tell me any secrets or tricks to the twin-I switch and/or installing the vac booster from the 73 to the 66?

 

it is easier to do with the motor out. i found that even if you are going to keep the radius arms from your 66 it is better to use the steering rods, tie rod ends, etc from the 73-79 donor when installing the disc brake rotor, spindles, etc. the proportioning valve on the 73 probably has the valve mounted on the steering gear top. directly under the brake booster. that style of mount makes it easier to change over. just use all the plumping etc from the 73. no need to mount the valve down where the original one is. pay attention to where the brake lines go when you remove them from the donor. spindle removal can be tough. good luck. jim.

 

Mike, I have done a couple of those conversions. First of all, just about everything is bolt hole exchangeable. The engine in that truck unless it has been swapped or rebuilt is most likely a 360 (390 bore with a 352 crank). I would get the engine freshened, along with the tranny, pull all of the parts (brackets, pullies, and lines) and paint them. It would make all things much easier to do as Jim suggested and have everything preped and ready to install. Pull the engine, tranny, I-beams etc. from the 66, clean and paint the engine bay and go for the swap. I don't know what your skill level is, but if it is not very like mine, you could get it done in a couple / three weekends.

In the cool still quiet of night, you can hear chevies rusting away.

 

 

Just my 2 cents but if the 73 has everything you want why not unbolt the 66 cab and bed and bolt it onto the 73 frame I here this is practically a direct bolt on everything DONE,Fatz

 

Thanks for the input! I will be using your help and it is much appreciated

 

I think that the rear frame section of the 73-79 is different than the 65-72 version. These PS,PB, twin I beam type swaps seem to be the most popular thing we are doing with our trucks. Someday, the 67-79 truck fans will wonder where all their parts have went and they will find them in our 65-66s!
