Thanks for that detailed information:-) i don’t doubt you for a minute and so it appears an error has been made in the Jaguar Parts Catalogue-(eBay item number 332230177416 and only £14.90 delivered )
regarding Vin 148574 as it is clearly there in print on page 149.
The parts book has been a great point of reference because it shows parts in their component order of assembly and makes stripping down/rebuilding much easier to understand
