64 A Body rear axle dimensions

[MoparMalch]

Does an 83/4 from a 67 and newer A Body directly bolt into a 64 A Body?

 

[Brad4406]

Yes. However, you will need the mounting hardware, i.e.: shock plates and u-bolts, from an 8 3/4 as the axle tubes are larger diameter than the original 7 1/4. Your driveshaft will need shortened or replaced as well.

If you get an 8 3/4" from a 1970 and later car, the brake line distribution block was moved down onto the tube and requires a different line set, and probably a longer hose!! I ran into this on my build as have many others!! Also as Brad says above!!! Geof

I understand you will need to use the emergency brake cables for the 7 1/4 rear- haven't got to that part yet and i ordered new replacement ones????

 

[Darter6]

Yes the 7 1/4 cables will work

That's great news, I have a complete Duster 83/4 with springs and 10" brake system including lines. Should be a direct bolt in. Any one know the driveshaft length with a 904 tranny?

 

[cosgig]

I'll get you a measure on mine and report back!! Geof

 

[MoparMalch]

Thanks Geof. I'll wait for your measurement

The bone stock shaft in my convertible is 49 5/8" from the center of the rear cup to the center of the front cup of the u-joints!

Hooking on the very rear of the shaft itself, on the rounded area that makes up the u-joint cup, to the very front of the rounded edge that makes up the front u-joint cup is 51"!

Hope this helps, Geof

Is the Dart longer than a Valiant and Barracuda being the floor is longer? Just asking being the OP did not state which 64 A body.

 

[cosgig]

That I dont know, Mark! I believe I read that he is working on a 64 Cuda!

 

[MoparMalch]

Its a 64 dart convertable with 904 and 83/4

The cuda's had a 111" wheel base, that darts I believe had a 108" wheel base... someone double check my figures.
