disc brake swap

[made2drag]

i am changing from 67 drums up front to 73-87 drop spindles and disc brakes. i have the spindles and ball joints on and now i need to do the tie rods. i guess i use 73-87 outers and 67 inners? which tie rod adjusting sleeves? there are so many to pick from. what is the best combo?

[my67chevytruck]

call Jeff at Classic performance parts. I believe they have conversion tie rods.

thanks for the info!

You need:
'73-'87 outers, and '67-70 outers (to use in the place of the inners so the threads will be opposite LH and RH),...

and some adjusting sleeves that have 11/16" threads on one end (the 73-87 tie rod end),... and 5/8" threads on the other end, (67-70 tie rod end).

Www.PerformaneOnLine.com sells the "conversion" adjusting sleeves.
This is how I know,... (my '69 disc brake swap)

is that a cut lowering spring? looks really short. i have bags and i think that your lower control arm is sitting as low as my bag and drop spindle on a 29" tire

could a 73-87 sleeve be welded to the 67 5/8 side? thanks for your help

Not a wise idea to weld together steering components. Spend a few bucks and get the conversion sleeve so you know the piece won't come apart on you when you are driving down the road.

[made2drag]

yeah, after i posted it, i wished i could have erased it. also $50 for the conversion sleeves isnt bad, and it would cost me 40 for the stock parts anyway.

another question: i bought a 77 brake booster/master cyc./prop. valve from junkyard. couldnt find good brake lines. where can i get brake tubing to use from the 77 prop. valve to 73-87 soft lines? or should i try to use the factory location for the prop. valve and use the 77 prop valve there? the faq threads are great, but i couldnt narrow it down.

[mclairmo]

Any Kragen/O'Reillys will have a good supply of flared brake tubing with the nuts on them. Just bend it yourself. If you need to, you can one end off, add a different size nut and re-flare it.

I have 2.5" drop spindles and 3" (Summit brand) drop springs from Summit Racing.
They are actually Ground Force springs in a Summit Racing box.

[made2drag]

thanks mclairmo, i will give that a try

The 67-72 a-arms will work with the later 73-87 ball joints.
No need to swap the entire arm,... unless you just want to.

[ah_5500]

really. thats awesome. so bolt in 73 87 balljoints up top and press in 73 87 balljoints below? add in some 73 87 drop spindles and im set with exception of tie rod conversion and 73-87 master cylinder? thanks again. also is this what you did? (stock arms)

Actually my drop spindles are for 71-72 trucks. (Swap meet item for $100)

It's cheaper to just buy the drop spindles for the correct year of truck you are putting them on. Then there is no need to change balljoints OR tie rod ends.
I wish I would have done that. It would have been much cheaper in the long run. (just the tie rod adjusters are $50/pair)

[ah_5500]

but considerin my 67 has drums id have to do some swappin around as discussed right? also i couldnt find the adjusting sleeves, could you link them to me? the ones i found said nothing about converting. do i just tell them what i need when i call to order or are they on the site somewhere?

[ah_5500]
