    TR4/4A Want to buy tr4 tranny for my tr3a

    I interested to purchase a TR4 tranny to put into my TR3A to gain synchro in first gear! I was also told that the TR4 tranny is 1/2" longer than the TR3 tranny (added synchro rings I guess). Does the extra 1/2" in length necessitate any additional fitments/alterations when installing?
