There are a few different cross mambers around for the EA.
The EA I has different mounting points on the chassis to the EA II onward.
The EA II has a 4 speed, which is the same length as the 5speed box. The cross member for this is a straight looking one.
On the other hand, the EAI needs a cross member which has a large curve in it to compensate for the longer gearbox. There is about 4 inches difference.
Figure out which one you need so you get the right one. Oh, and the EA I manual cross members are not easy to get a hold of.
CAUTION: Slippery When BOOSTING!
