Early A-Info

MOPARFIVE said
Hi everyone. I have a 63 valiant that I want to install a late model A-body K-frame and disc brake set up in the car. I have all of these pieces from a 74 Dart. Is this a bolt in project or do the early A-bodies require some modification to do this install? Also what trans mount should be used to install later model 904 into this 63? Do I use the late model or the early trans mount or do I have to fabricate one? (this is the piece that bolts trans to torsion bar crossmember) One last thing is what headers will fit a 63 Valiant with small block in it? I want to go under chassis. Who makes a decent header for this application? Thanks to anbody out there that can share some info to help this project along.

The K-frame will not interchange, nor does the K-frame need to be changed
to add a V8; in a 1963-66 A-body car.You only need Schumachers kit.

You will need a sledghammer to bash in the firewall,
as needed where the distributor and rear of the valve covers will hit.

I suggest use 1964-66 273 Exhaust manifolds, headers are a major hassle
in a 1963-66 A body.

The disc brake conversion is not too hard to do.
