Our 1965 +4 two-seater came with two plywood wedges resting on the floor and supporting bladder  (whoopie!) cushions. After we bought it, it was completely re-upholstered and foam cushions  replaced the aged bladders.

The plywood wedges were retained and continued the normal characteristics of the Morgan drive by amplifying the most minute road irregularity to every part of the anatomy. I'm almost sure that if we drove over a dime we could tell if it were heads or tails. Most 2 seaters of that vintage came that way. On the other hand we have a number of four-seaters in the MOGMOG club and it is with some jealousy that we envied the coil-spring seat supports. Those cannot be fitted to the two seater. We queried Morgan Spares and Melvyn Rutter and found out that a pair of bucket seats would set us back $1,350 plus shipping and any difficulty we might have in installing them.

A month ago we made a big decision - replace the wooden (kitchen chair) wedges with spring wedges
of the same dimensions. I went to Home Depot and bought ¾" angle iron and a large quantity of springs of differing lengths (some were called hobby springs—from the hobby horse I presume). I found  out that there are 6 Home Depots in the Houston area and I had to go to every one to get a sufficient  quantity.

One of the charter objectives of the MOGMOG club is for members to help each other in Morgan activities. This project turned out to be one of those. I sawed and drilled and Andy Martin bent and welded. - I attached the springs.

I drove home from Andy's and it was as if Houston had paved all its streets overnight. We felt the difference (or I should say not felt) driving the 400 miles to Bluebonnets 2000 in Smithville. We didn't  have to get out of the car every 75 miles (at least not for the same reason!)
.
While we were at it, we took care of another inconvenience. Morgan is 6'8" and I'm not exactly  short. When we drove, the top of the windshield acted like a wide (very wide) crosshair. We  lowered the wedge so that we're sitting about 1½ lower. Now we can actually see through the windshield. We consider the project to have been, to be and to continue being a rewarding success. And all this was done at very, very minimal cost!
