One of the backing plates for the roll bar consisted of this angle iron to improve body stiffness.

I know some don't like them but roll bars don't bother me aesthetically and this being a V8 conversion I wanted to try to add some stiffening to the body. All of the mounting points are backed with steel plates and grade 5 bolts are used all around.
I believe you could pick up the car by the roll bar.

Leather Mazda Miata seats were fitted. The original mounting points were used for the front bolts and two new holes were drilled for the rear. In addition, backing plates under the floor pan were added to the back mounts.
I used these seats because the MGB seats were trashed and it would have cost more to fix them then it did to buy these LEATHER seats, and the almost bolt right in. In addition, the Miata seats provide more support and are more comfortable in my opinion.

Glen Towery's mounting brackets were used for the tramp bars. The fine thread bolt allows precise adjustment of the tramp bars.

I did not use a panhard rod. The tramp bars seem to do a very good job of locating the rear end. Under normal street conditions, the rear end really digs in under hard acceleration. Perhaps if the car was being autocrossed or raced, it would be a different story.

You can also see the Koni tube shock mounting point in this picture. The lower shock mounts were sourced from Autozone in the HELP section.

To keep the stock MGB rear end located and put power to the ground adjustable tramp bars were made. Glen Towery's tramp bars were modified by cutting them, welding a nut on to the longest end of the hollow bar, and a 5" long fine thread grade 5 half inch bolt was welded to the other end. The bolt is threaded into the nut welded on the bar and a jam nut keeps it in place. Probably I didn't need the jam nut since it is located and prevented from turning with the mounting brackets, but why take chances.
The nuts welded onto the bars are ground smooth in this picture. The nut that is clearly visible is the jam nut.

RV8 style headers were ceramic coated inside and out by Jet-Hot to increase longevity and decrease temperatures in the engine bay. Ceramic coating was expensive should pay for its self in the long run, and they look good.
