360 la vs magnum rear main seal diameter ?

[1bad360duster]

Hi I ordered a stroker kit for a 98 magnum block and was asked to measure the rear main diameter. I thought the 360 la and magnum should be identical? I don’t have my motor out yet so I can’t measure. Anyone have any experience or input? I did hear that the 318 magnums may be .01 smaller but not sure that’s true.

Check Rockauto. This seal is for a 98 1500 with 5.9.

Thanks guys. From what I’m finding the difference is in the 318/340 la to 5.2 magnum stuff being .01 different. Looks like 360 la to 360 magnum is identical. If anyone has more info I’d appreciate it. Thanks

I just realized there are two threads on this question. I put measurements in the other one.
