brake and axle questions....New Member

[jcf2403]

i have a couple of question, which some of you may think thet're kinf od dumb, but this is going to be a new experience for me. I have a 1964 3/4 ton 2wd fleetside long bed. i want to change the wheel bolt pattern form 8 to 5 and convert the fronts to disk brakes.

Now my questions are:

I've been looking at different websites for the parts and so far every single one 'ive seen only offers kits for the 1/2ton. will these kits also fit the 3/4 tons or not? if no, why not?

as far as the rear goes can i just switch out the axles or do i have to change the whole drivetrain?

thanks

You have to change out the whole rearend. You can use a 71-72 rear end and they are already 5 bolt. If you have leaf and not coil springs you might be able to use a later model rearend but i'm not totaly sure of this.. If you have coil springs then you are better off looking for a 71-72 rear end... They bolt right in..

do only the 71 72 rear ends bolt right up or are there any other rear ends that will fit it.

I can reccomend LMC truck, they have the 5 bolt discs to change over without swapping your axles (front or back) My friend did it to his 1966 front and rear without any problems.

If he did that to a 3/4 ton then you can do it too.. The 71-72 1/2 tons are the only ones that are 5 lug with coil springs. In 73 they switched to leaf springs.. Also if you switch to a 1/2 ton rear you can put higher gearing in for better freeway speeds.. I forgot to mention that you can probably pick up a whole rearend for less money then to just buy the axles... I got mine at pick and pull for $110...

Yeah, I was also thinking i could get the whole rear end at cheaper price. Now as far as the Front brake kits go, do the kits they sell on LMC truck fit the 3/4 tons? I'm asking this because it specifies that it will only fit the 1/2 tons.

You will have to change out the ball joints for half ton... I used the whole front suspension from a 75 1/2 ton.. Steering box, center link, idler arm, upper and lower control arms. If you do this you have to redrill for the idler arm..

Whats the difference between the 3/4 ton and the 1/2 ton ball joints? Is it alot of trouble fitting the disc brakes on a 3/4 ton?
