4.5" bolt circle in 65 valiant

[sdflenner]

Is there a 8 1/4 or 8 3/4 with the 4.5" bolt pattern that will bolt straight up to my car with no mods.Just remove and replace.The car is a 65 Valiant

No, unless you build one. The '73&newer A-body 8 1/4" is as much a bol in 4.5" pattern rear as it gets, but the pinion is longer than the 7 1/4's os you have to shorten the driveshaft.

DartGT66 is right; the 8¼ will give you the most affordable and easiest mod. There was no 8¾ with the 4½ bolt pattern manufactured for A-bodies. I also read, I believe it was in Mopar's chassis book, the 8¼ will need some mods with the parking br

Depending on the amount of torque you want to produce, the most affordable I can think of is use a rear axle out of a 67-72 A body with more rear wheel backspacing. Because of the small inventory of wheels made for this application, I would suggest having your axles redrilled to 4.5" circle. This allows you a larger wheel selection to choose from. I had this done for these very reasons. I sent my axles to Moser Engineering who plugged the old bolt holes, welded and lathed the flange, redrilled and threaded the new holes, and installed new studs for $89 inluding shipping. If you plan to make alot of power, then aftermarket axles may be necessary anyway.
