I’ve got multiple pairs of these billet caps nearing completion and figured I should put the listing up sooner than later. I will offer them in pairs for position 2 and 4. I can sell you a cap for position 3 thrust bearing as well but it would be up to the installer/machinist/end user to machine fit the faces of the new cap to the block to blend them together so the bearing seats properly and results with the proper amount of thrust clearance. With my current shop rate, material prices, tooling prices,etc the math for this batch of caps came out to $160 per piece. Shipping/insurance is extra and varies depending on location and if you want two or three caps. Please direct message me if you would like to purchase. I accept USPS money order, certified bank checks, and personal checks but there will be a waiting period for those checks to clear before I ship you the parts. Please include your shipping address and if you want two or three caps (or more) so I can figure out a total for you with shipping and insurance included. 
Thanks for the space Jay,
