Aren't these the lower control arms preferred when doing a front wheel disc conversion on a 67 and up A body?
They have the larger ball joint hole, plus the sway bar tab, preferable for the big block tourque?
No sir. Ball joint taper is the same as all the other A-body lower control arms and the ‘73-76 sway bar tabs will not work with a factory ‘67-72 sway bar.
The ‘73+ tab location will work with the Hellwig 55917 front sway bar for 67-72 cars and the 67-72 Hotchkis sway bar though. But not the factory 67-72 bars or any 67-72 front sway bar that uses the factory tab location for those years.
Only the upper control arms got a larger ball joint taper 73+. The lowers were all the same with the exception of the sway bar tab locations.
And great work as always Jim, those are some good looking LCA’s. :thumbsup:
