Morris does have them. You will have to pull the intermediate shaft to replace it. That will likely be a PIA as it most likely has rusted up well enough that it won't collapse. You may want to consider replacing that shaft as well as the u-joints in them wear out and cause a lot of play. It will make repacing the bearing easier as well since you can just cut out the old one. The shafts run around $120 and $20 for the bearing. The other option is remove the bolts holding teh steering box so you can lower the shaft enough to get it off. Search this forum there are a couple of go-by posts.
