OK my new to me 78 has had d shaft probs from the beginning so i went to te junkyard and scored d shafts from another bonc of that year 78-79. Damn universals are larger 1350? So I scored the yokes- the 9 inch fit fine but the t-case side is much larger seal diameter- the question is - is the shaft larger too or can I go & score the output cover and get away w/ that swap to finish the deal. Any body dealt w/ this headache before? PS thanks for the help w the steering box issues.
