Need 7mm bolt for chain rail (timing chain)
 

I am almost done rebuilding the engine of my 2000 XK8. I had to replace the left (driver's side) head. The original head was p/n XR83-6C064-AD, but I had to use an updated head with part number p/n XR83-6C064-AE. My problem is that I cannot locate a 7mm bolt I need to hold the chain rail in the head for the timing chain. Everytime I order the bolt the dealer sends a screw that is too big. I assume they are sending me the bolt for the p/n XR83-6C064-AD head. I need the 7mm bolt for the p/n XR83-6C064-AE head. Does anyone have this bolt or know where I can locate one? I have been told that Jaguar has changed this part and/or part number several times. Help.

Thanks.

Check these guys out. If you have the specs they will probably have the bolt.
