[Tigers] tiger rear end

It is the ring gear that is threaded either 3/8'" or 7/16", not the housing. The housing has the through holes, and I've have never seen any 1/2" threads or holes. Check your memory. LOL
You could use stepped bolts, but that is only needed when you install American ring gears (3/8" threads) on British housings (7/16") holes. Generally it's the other way around, namely original 2.88 British gears with 7/16" threads on an American differential with 3/8 " holes machined out to 7/16".
IMO sleeves are much cheaper. Just buy the correct tubing and slice it the thickness of the housing lip.

 If memory serves, when the differential itself has 7/16 inch threads and the ring gear is machined with 1/2 inch diameter holes there are two options:

Use a stepped ring gear bolt that has a grip (unthreaded portion of the shank) of 1/2 inch with 7/16 thread such as ARP 350-3004

Use a bolt that is fully 7/16 inch in which case 1/2 to 7/16 ring gear bolt sleeves are used such as Yukon gear YSPBLT-028.

Neither is needed if both the ring gear and differential are machined/threaded for the same diameter.
