    I just did a 465/205 swap from a 700/208 combo and i had to drill new holes in my crossmember. I only had a single hump cross member but i thought everything went smooth

    if the tcase adaptor is short then w crossmember is needed. if tall adaptor then flat one is needed. and will probubly need to drill holes.

    Thanks. I think I've figured it out. I have a short adapter on my 205 and will need the w style crossmember. I am also going to have to driill 2 more holes.
