Sierra column to escort rack

Evening chaps,
What bits do I need to get from my Sierra column to my escort rack please. Got in a muddle with what I need.

Sierra column, lower column with Flexi disc will work, you will probable need to cut and lengthen to suit. Alternatively you can use a splined shaft with a triangular coupling to fit the upper column and a UJ to fit the Escort rack , ageing the length can be altered to suit . Rally design and Car builders solutions sell the parts . Also be aware that the Sierra lower column was available in at least 3 different varieties of shaft diameter which may cause clearance problems. Have a look on here for info on using a self aligning bearing instead of the Sierra bulkhead bush.

Cheers buddy. The self aligning bearing is one bit I'm struggling in finding info about.

The bearing is easy enough.

Your steering column pokes through the bulkhead. Itís supported by a two piece plastic bush inside a rubber one. To aid self centring by reducing friction you ditch the outer plastic bush and the rubber bush. You keep the inner one that fits on the triangle and fit it into a self aligning 25mm bearing and bolt it to the bulkhead.

Itís then a case of cutting and sleeving the Sierra bits.
On the to do list is replacing the 30 year old rubber coupling on mine with a nice uj but itís a £100 touch plus work.

Does replacing the Sierra bits make much difference to self centering?

Not a lot, but when you only have half what it should be every little helps.

Iíve seen some of the plastic bushes with deep grooves worn in to them
