Advice pls, crutch strap fouling seat rail

Hey All, 
I'm looking for some advice, hopefully, I've done something wrong or someone has a tip to resolve the challenge having been through the same thing.

A couple of weeks back I installed the crutch strap kit as supplied by Caterham.  It's all fitted fine, the harness is so much better.  However, there seems to be a small drawback.   

The retaining triangle section of the straps which are bolted between the floor and bracket are fouling on the seat rail, it prevents the seat from traveling all the way back.  As a result, I've lost around 4 cm of rearward travel on the seat position.  I measured between the seat back and the dash on the 420 and 620.  The 420 has the crutch strap fitted and there's around 4 cm in it.  

I've put an endoscope down to have a good look with everything fitted.  It all looks fine, nothing daft, just there isn't room.  

Has anyone else dealt with this?  The loss of 4 cm makes a big difference on an S3, the seat feels to far forward now.

Thanks

Thats odd nothing fouls mine, are the seats in both cars set at the same angle.... adding washers under the front reduces reward travel very quickly as the seat is naturally tipped backwards.

Cant visualise which part of the seat is fouling.... and its way to dark windy and wet to go out.....

Thanks for the response.

I've got some photos on the endoscope, but it's a cheap jobbie from China, so I need to put in a new flashcard as I don't trust the one supplied.  Once I've done that I'll post some images.

Hopefully you can see the retaining triangle is fouling on the rail, and stopping it from going further back.

Hi Mark, I have different seats and belts to you so I don't know if this is helpful but I have had a look at mine. I have removed the seat base to get a view. The crutch strap mounting points appear to be inbound of the rails so they don't foul. See the photo. Mine is an S3 with lowered floors.

Mark,

have you routed your straps under the seat or around the side - cant make it out form the photo... they should go directly under the seat ie between the seat runners.

Yes I've routed the harness inwards so that it passes under the seat. 

This is pretty much how I laid it out, the yellow arrow shows where I think it fouls.  I have adjusted the buckle backwards so that it doesn't foul under the seat base.

Steve, 

I think yours shows the buckle, I believe mine is fouling on the retaining triangle.

Thanks

Mark

Cant quite make out form you photo mark but it appears that the rear of the runner protrudes a fair way from the back of the seat... my are pretty flush..?

For comparission how many Tillet spacer washers are you running under the front and rear between seat and runner (and what thickness)

Yes, that's normal in my experience.
