MGB Trans. Mount Bushings

The following is my recommended procedure for installing the two rubber bushings (Moss # 280-055) on the 1968-on MGB transmission rear mount.
The smaller of the bushings two flanges is 1 1/4" in diameter and about 1/4" thick. The hole through which it must pass is only about 3/4" in diameter. None of my usual brute force and ignorant approaches (i.e. screw driver poking) were of any help when attempting to install these bushings. In fact, more time was spent chasing them across the garage floor, than in concluding any constructive work.
It dawned on me that the problem was similar to installing the windscreen rubber on a Triumph 2000. So I developed a procedure along that line.
First, secure the yoke in a vise, oriented as shown. Tie off one end of a thin cord, in the direction of one end of the yoke (I used the vise base for this). Loop the cord and pull it up through the yoke hole. Pass the loop about the bushing as shown, and place the edge of the bushing flange into the yoke hole. It helps to oblongate the bushing as you do this, with your free hand.
Initially, you should pull the cords almost parallel to the bushing groove. But, as more of the flange begins to enter the hole, you should change your direction of pull downward, until eventually you're pulling straight down. In this manner, you will gradually peel the flange circumference through the hole.
A lubricant, like Armour-All, will make things easier and protect the rubber from chafing. Tying off the cord leaves one hand free to manipulate the bushing, and also to change the pull angle of the cords. Obviously, the wiser you are at choosing your tie-down point, the better this procedure will work.
That's it, you're done then! With more time for the important things, like popping open a can of Tennent's 80-Shilling Ale and toasting the Empire.
