    I'd like to convert one of my 64 valiant convertibles to a 4 speed, 1 already has a 318 swap so that will probably be the one, it has a 727 in it now. I'm hunting for the floorpan hump and have a 69 a body 4 speed, it has a Lakewood scattershield that Is overkill so will find an alum. Bellhousing Questions are
    Will later a body pedals work or do they have to be early?
    Will later a body Hurst shifter and rods work?
    Can a later hump work on the 64 pan?

    You will need the early bolt on pivot for the early z bar.
    You may find clearance issues with the big sb later yr/style bell housing. I remember when I was messing with them it was something lame ..like I had to use a small clutch/flywheel or 10in truck style from a slant...and early bellhousing for the early car to get by without cutting the transmission hump at the firewall for clearance and adding and 1" or so...but I'm not certain since it's been a minute.

    1.Nope early pedals only 63-66

    2.if you use 10.5 clutch you will need aluminum bell housing with special torque shaft and ball stud brewers sells conversion parts. if you use the smaller flywheel with the original 273 bellhousing you can use stock torque shaft ball stud etc

    3.i think all four speed shifter and rods interchange except the later OD version

    4.i know a guy who put a 67 hump on his early abody it looks like shit.

      If you keep it simple by using a 273 flywheel and bell from a 64-66 A body you can just bolt it all in.You can use a 10 inch clutch with this set up.I did this in my 65 Barracuda with a 318 and it worked really well.No cutting other than for the 4 speed floor hump, no fabricating It all just goes together with the right stuff. It really comes down to what you need in terms of car use.It it's a nice car you just want to drive and not abuse then this is the way to go .If you want to race around and beat the thing then you need to go in another direction.

        Thanks for all the info, Looks like I will get rid of the scattershield and go with the 273 bell and 10" clutch and stick with the stuff that will just bolt in and go!

        Looking for these?

        The hump is an old aftermarket fiberglass piece.

        I'll message you with my email address so you can contact me about them if you want to.

            This is a later A hump for comparison, they are quite a bit different;

              Interesting......

              I wonder what the one I have is then, anyone?

              It had a parts tag on it saying early A-body, but maybe not......

                  The 64-65 had the round hole in the middle of a raised ring as shown in Cudabnu's picture. Starting in the 66 model year, the shifter hole was oblong and flat.

                      according to brewers, the tube should be 7.5" long

                      According to Brewers
                      67-76 /6 is 8"
                      67-76 V8 A body is 7"

                      they dont give a measurement, but could be:
                      1963-1966 A-body applications when converting to 1968 & later 10.5" bellhousings

                      Let me throw this out there....my 64 valiant already has a 727 stuffed in it, so can/should I just go to a later 10.5" bell housing and conversion Z bar?
