digger;
I found some bishop reference from afv interiors... I know they are off-line. How I don't know but when I typed "25pdr" "bishop" into the MSN search up came the page from afv interiors. So give it a try and see if you can download the file and save it. If you can't email me and I will zip and send you a copy of the information.
As far as finding a Bishop Kit. I think you might be able to find one at www.udisco.com ask their information email to search the stock for you. Don't depend solely on what the website listing shows.
Cheers;
Gregory
