Anyone know of a good place to get a rebuilt 3B my 82 BJ42 has has had low oil pressure for years and it starting to loose power… and it doesn’t have power to loose . Also anyone swapped a 6.5 GM… I think the HUMMWV is 24volt as well … don’t know shy to do next

Buying a rebuilt 3b off the shelf is a tall order in the USA. Having your original 3b rebuilt as long as there isn't a hole in it is pretty straight forward although not every part is still available (im not sure what would be needed in your rebuild) . consider the 13bt, 15bft, 1hz or 1hdt before the GM 6.5. They can be made to bolt to a h55. You already have fj60 steering so your part way done. 24volt vs 12volt factor is small by comparison.
