I swapped in a 460 in my 79 a lil while back and w/ my D44 I knew I was going to break axels and joints, especially w/ a detroit and 37s. Bit the bullet and bought Warn shafts and CTM joints. Been out hard wheelin twice and abused the hell out of them and they are good as new. Only time will tell, but I feel comfortable w/ this set up. Figured it was worthy of mentioning here. :mrgreen:
