Hello Dave, I am new to being registered on this forum but have been watching your superb efforts and many of your interesting and inventive ideas. Great work and support for the members of this forum.
I really like your idea of flaps to stop the wings being damaged by flying stones..Thank you I will make up a set. Yes, very surprising this kind of thing ios not a factory option or on the shelf somewher.
Two years ago I acquired a 1968 Plus 4 that I bought (in almost scrap condition) Have done a bare chassis refurb and had good use out of it last summer.
It is a super project and I have learned a lot from you and others at Talk Morgan,also Lorne Goldman and GoMog in Canada where I live. Could not have done it without all the snippets of info I gathered. Never having owned, or even driven a Morgan before I would have been completely lost..and it is a good feeing to know there are others struggling with all the same things, even if I can't see these people.
Front axle tips. It is an old topic but one I suspect may be of interest to all with the Morgan sliding pillar suspension. When doing mine I used needle roller bearings and suitable adapters on the top of the main springs and on the top of the rebound springs. These are rated to carry enough load for this job. They work very well to minimize wheel wobble. Even removed the old saw blade thing and kept all the old parts together in a box. In the aluminum adapter plates for the neddle bearings I incorporated "O" rings that work as wipers to keep grease in and dirt out.
To protect the lower part of the shaft from dirt I used medical bungee wrapping like you would use for a sprained knee etc. It is an elastic open weave bandage. A few turns of that There is room for about 5 turns) with a plastic tie each end securing it makes a very good and flexible dirt filter that can be easily removed for shows and changed when dirty.
For the main spring I made a vinyl sleeve that reaches the bottom of the main spring. It clamps to the top needle bearing adapter with a hose clamp (screw clamp hidden from view, and velcro down the sids (at the back. This can also be easily and quickly removed for shows etc.
Thank you so much for your sharing your knowledge. david (Safari-1)

Hi Dave,
Something I tried last summer that completely removed the steering "wobblies" (in addition to the needle thrust washers on both main and rebounmd springs) was a (temporary, now permanent) diagonal 1/2" aluminium box section between the right hand front of the chassis and the left corner of the chassis at the rear left corner of the engine space. (My car is left had drive if it matters). The wobbling was not as bad as I have heard some people describe, but it was there at about 40 mph. (Now it is not).
I felt that the front section of the chassis might be wracking in response to the wheel wobble, sort of feeding on itself once it started. Since the wobble disappeared immediatley after installing this brace this seems likely. It would not need much of a wracking movement to start things going in a sympathetc oscillation fashion.
I have already cut and will soon instal a 1/8" aluminium sheet covering the bottom of the engine space and bolted to the chassis at three locations each side. This will stiffen everything enough to stop wracking and still allow chassis flexibility. A + _ 6" hole under the engine oil drain plug will give some ventilation.... May even make a round cover with two retaining screws for this if ventilation is adequate with this opening closed..
There should be plenty of louvers for the cooling air from the radiator and engine space to escape.
A slicker underbody surface will almost certainly make for less wind resistance, perhaps quieter and less under body turbulence.
This mod will not interfere with any of the visuals of the car, and can easily be removed for shows etc.

Don't know how old your car is David, but it is worth checking the triangulation plates just ahead of the bulkhead (firewall) that are welded to the chassis legs. Rust can build up between these and the chassis, forcing them apart and removeing the support provided to the chassis front end. If that has happened, it is worth fitting the plates from the later chassis, which are considerably longer and give greater support.

Hello Graham, Thanks for your reply, points valid and well taken. It is a 1968 Plus 4 four seater with 34,000 miles in canada, almost certainly never driven in winter or it would be dust by now. It sat unused for 15 years in a barn where I found it with a baffed TR4A engine......in true "barn find" condition it needed everything. Still finishing him up.
I had the front axle frame out when I did the bare chassis job. There was some rust but not serious. Bottom of the scuttle skirts too, replaced metal there.
Installed the brake braces to stiffen up the front suspension frame too.
Do you know if anyone making trailing arm rods and coil-over-shock kits and Panhard rods for the rear? In my mind I see removing the cart springs completely and using trailing paralelogram rods usong the forward spring mounting bolt and one fabricated above it. Using adjustable height and rate AVO (or similar)coil-over shocks. Without the springs there would be plenty of room to put a panhard rod, or a Watts linkage...and probably 40 lbs less weight with the springs not there.
Best regards david

Hi David, It was worth checking as that was part of the problem with my '76 - took a year or so before the true cause of the wobbles was found! You want to completely revamp the rear suspension? Talk to Peter Mulberry: http://www.mulfab.co.uk/He has developed a complete replacement rear end for his own car (and a front end too). Whether he is selling them as kits is another matter... Cheers,
