Steering shaft length

[MikeB]

I'm going to get MK sportcars to make up my steering link as its one of the key parts I want ot know is 100%.
They do them for a very reasonable £40 but I wanted to check the length end to end, I've read IVA man likes to see there is enough room for the collapseible bits to work in teh main column.
Have you got any pictures of dimensions for the link and how far the upper column should stick out into the engine bay to allow the collapse mechanism to work right?
Thanks

Mike
