Wow, someone put all that money into it without upgrading the tranny!?! Your easy choice is the AX-15, however I don't know how it handles the D60's, someone else can chime in on that. The AX-15 is almost bolt in, you just need to collect some parts from newer rigs. There are a couple DIY's for it. Look for the 93+ bellhousing for the external slave.
