1G Jay Racing Main caps Questions????

[SasaniFab]

So I recently picked up a awd transmission and transfer case, the guy who I was meeting on craigs list also brought a 6 bolt block and some axles as part of the deal. When I showed up two guys stepped out of a rusted out jeep Cherokee, one didn't have a shirt on and looked like a meth addict the other could pass as a heroin addict on a good day. So he pops the back hatch, the transmission looked good and the transfer case was clean and was the beefier type with the cast iron housing. The block was very clean but I noticed he didn't include the main caps. He basically assured me that he forgot the caps and would ship them when he got home. I took him for his word and he never shipped the caps, So I paid 500 bucks for a good awd 5 speed and transfer case, 4 axles and the block. At this point my only option is getting a set of the jay racing main caps. Im totally aware that it requires a Line bore/hone. Have any of you guys used these?
