yes,
well thats how I,ve done mine, but its NOT the only way to achieve the desired result .
there has been other builders using a different bearing carrier thru the bulkhead.... I think Ash G has some pics of how he did his in his build photos link.
Just an after thought......which steering rack extensions are you using ? if its the ones detailed in the book, they are wrong( too long ) & makes the wheels point left & right at same time
.
cheers
