Sounds like you have a 67-70 frame.
Without pics it’s hard to tell.
If there’s no indent behind the steering box it a 67 frame.
If there is it’s a 68-70 frame.
These trucks are old.
Lots of parts have been changed.
Please post several pics of your suspension.
Steel brake lines connect to the rubber hose behind the crossmember on 67-69 trucks..

I’ve been preaching “63-70 conversion spindles” for many years now.
I’m not sure why this info is not getting out.
There’s no need to use 71-72 or 73-87 spindles.
These conversion spindles are the same price and require no balljoints or tie rod changes.
Buy from places like Summit Racing that offer free shipping.
I like ECE (
www.earlyclassic.com) for 67-72 parts.
But wilwood, mcgaughys, western chassis, belltech, and even CPP make good spindles.
Hope this helps.
Get the word out to use Conversion spindles!
