Newbie looking for 10.5ring gear 8 bolt axle housing gasket

[biglooni6x10]

I recently purchased my first truck 99 k2500 454 with the 10.5 ring gear ff axle.I'm currently getting all the parts together to replace my inner and outer wheel bearing. I'm having trouble finding a rear axle housing gasket with 8 bolts For a 10.5 ring gear. Auto parts stores only seem to carry the 10 bolt gasket.
I was wondering if any of you vets would know of a good source for the 8 bolt axle housing gasket as Im not sure if I can simply make one out of rtv. Thanks

You can make one from RTV done it about two dozen times but a 14ff with only 8 diff cover bolts?

are you talking about the pinion seal because a 10.5 should have 14 bolts holding the cover on

The pinion support is six bolts, axle shafts are eight.
