Cut away all the old bulkhead just leaving the top panel and the fixing holes for the windscreen motor. Also put a semi-circular cut the top of the panel for the air filter this let me move the bulkhead forwards by 20mm.
Trial fit of the roof. Always intended changing the intake and twin carbs setup for a lower intake and a single carb. But with roof on the position of the bulkhead is to far back in relation to the door openings and were the door seal edges need to be extended from the chassis onto the Jag frame/roof. So I need to change the distributor and make a new bulkhead so the bulkhead can be moved forward and sit over the distributor and up against the single carb.
The plan was to buy an XJS windscreen and seal, fit the seal to the windscreen and then build a frame to fit the profile of the windscreen/seal.
Anyway the aftermarket seal was too big for the windscreen so I checked the seal specification with the supplier who told me the seal is normally big on the glass (50mm) but not on the frame, two piece seal you see (I got a refund)
So I went to the scrappy to get a frame, once at the scrappy I found out that the windscreen wiper mechanism is a lift out unit that fits into the front valance (great stuff) so why not just cut out the windscreen frame and quarter of the bulk head. Then I look at the roof and thought why not. The scrappy man was a bit confused.
