For someones future benefit - I found a good shop staffed by ex Ford
truck mechanics who replaced the manifold bolts on my V10 Excursion.
They did a great job at reasonable prices.

The shop is Roadrunner on 30 Brydon Drive in Etobicoke (Rexdale Blvd area) their number is 416-742-5414. They also do work on the diesels.

Thanks Rob
