I wanna do a disc conversion in my 69 barracuda 1 reason is I want to have the 5x4 1/2 lug pattern instead of the 4 inch they don't sell any nice wheels in that pattern also I just want the reliability of disc does anyone now of a budget conversion I can do

 

73 up A body disks

 

and he will still have sbp on the rear?

 

Yeah want the 5x4 and a half through out the whole car

 

Then you will. need new axles and drums for the rear drilled for 5 on 4 1/2.

 

Should I grab a full rear end of will the axles fit in existing rear end

 

Remember "A" body drums and axles are narrower (bearing to flange) than the others.

I believe mopar mentions the conversion to stock later model front disc brake assemblies will widen the track about 3/4" per side . The wider front track gives the appearance of crabbing from both sides!

I have had a small pattern set(axles and drums) drilled to large pattern using "A" body the 7/16 wheel studs that worked great.

It may be a better (but $) route to do a complete disc kit on all four corners.
