Looking at upgrading my 1999 cam plate from spring loaded tensioners to hydraulic. The following is a description from an auction, I understand there is one hole on the back of the cam plate that will need to be blocked. Will these cams fit into my bearings? Any other issues you guys see with this setup? Harley Davidson twin cam 96" cams , cam plate ,oil pump ,gears,chains ,hydraulic tensioners and lifters this is a complete drop in ready to go set up. The oem cam plate number is 25358-06 Is there any questions I should ask the seller of this product?
