If I'm not mistaken Hot Rod Wheel (HRW) went out of business several years ago along with Canton heads (sister company). The same cases are now sold by Moser. I'm not sure if Moser makes 'em or not.

The post concerning WAR cases is right on. If you aren't sure you have a nodular case I'd pass on it and get something aftermarket.

also note this. some cases use a 3.06 od side bearing and some use 2.89 od side bearings. i figure its a toss up. 289 have a thicker cap witha smaller bearing and vise versa.. either cap will use the 31 spline axle. with the correct side bearing. i recommend taping the main bolt holes as deep as you can and using either studs or as long a grade 8 bolt as you can [even to cutting an 8 to length. you should also have the bolt head seats spot milled to be square. the factory seats are not real good and the factory cap bolts are way short. tap the pinon support bolts as deep as you can and use longer grade 8 bolts with grade 8 washers there also. the cast iron Daytona support is the first best step. next is the bigger bearing supports. and there are several to go with choice wise. some use a big tapper roller some use a ball bearing, do some checking on your own as to what you want. but use something other than the factory, unless you are bucks down.
