Don, I'm not able to see any photos. Anyway I do have some comments after seeing your Flickr album.

One photo shows the fiberglass 'Shirt' that covers the MGB IFS. I had to cut a small section out of the left rear corner for the steering shaft to connect from Ted's Rack to the MGB column. It is a triangular shaped section about 100mm high and in proportion it resembles a 30-60-90 Set square. Your 'shirt' is not shaped the same as mine so yours may be different. And Ted's 2" wider unit may fit a little different to mine.

After looking at photos of your (Ted's) IFS. And I know you got the 2" wider unit. I'm not able to tell what is wider. Are just the 'A' arms longer by an inch? Did he move the shock tower to a different location so that it will not bind with your chassis? So I'm not clear on this.

I totally re-engineered the MGB column using stainless steel tubing with custom machined UHMWMDS shoulder bushes at both ends, A Bronze thrust washer for the turn signal canceling pin to ride against and locking collar at the bottom end. You can see a picture in my Album here on the forum. EDITED 2015. The UHMWMDS was a BAD choice for the steering column. As the engine bay heated up the inner steering shaft would jamb tight and steering became downright dangerous. See my Facebook photo album which has a lot more photographs of this work.

The MGB column is poorly designed (Junk) with an ill-fitting split plastic bush at the steering wheel end and a felt bush (yes Felt, Union hat makers needed work I guess) at the universal joint end. I could pull the steering wheel in and out more than 3/8" even after my first rebuild to MGB specs. I pulled/pushed the column in and out and after turning the wheel a couple of times I mangled a new turn signal switch/horn contact finger.

The column is not too much of a problem in the MGB as it fits directly from column to Rack with one universal. For the Cobra an intermediate shaft is used with two universals this setup can be pulled and everything gets longer. This slop I'm sure, contributes to inaccurate steering.

Since I wrote this post in 2011 I have totally modified the way the MGB steering column connects to the FastCars IFS. I Connect directly from the MGB to the FastCars IFS with one sliding DD steering intermediate shaft. Also makes removing the IFS or the steering column MUCH MUCH easier. This is the only way to go!!!

Regards,

Arthur
