We have sold my wife’s TR6 and consequently the enhancement and maintenance parts I have accumulated are now being offered for sale. I will start with some of the enhancements.
Most of the parts that make up the steering column are no longer available. One of the issues with the TR4/4A/5/250/6 steering column is the rubber “donuts” that deteriorate over time. When they tear, you have absolutely no steering control. Revington TR has developed an uprated lower steering shaft (https://www.revingtontr.com/product/rtr3634-bk/name/steering-shaft-tr250-5-6). This unit sells for 128 pounds plus shipping and taxes. I have a new unit for $200 (CDN) plus shipping or I am happy to bring it to a future TTC event.
