Hello-to remove the steering shaft first, pull the steering wheel off the end of the shaft. Next, remove the key that is underneath the steering wheel. Assuming that you have the crown off, remove the two bolts holding the bearing race off the front of the steering bolster. Dont damage the bearings as they can be costly. Finally, unscrew the steering shaft and worm gear off the front. The shaft comes out from the front. You might have to loosen the jam nut off the back of the bolster. As far as sleeving the engine, it dousn't have sleeves. You can take the block in to a machine shop and have it sleeved but that can become very expensive or if possible, have it bored out and just put oversized pistons and rings in it.
I hope this can help-Mike
