im trying to research the compatibility of my 1st gen 6bt and the nv4500 bell housing from a 98 v10. So far wat ive generally heard is that they bolt up but i will need to get a fly wheel from a 2nd gen. Can i get confermation on any of this? Does the 2nd gen 12 valve have the same bolt pattern as a v10? And does the 1st gen have the same bolt battern as the 2nd gen? I know this conversion will be alot of work and headache but i like tweaking on things and i think if i can bolt the tranny up i can hack up the rest to fit (with some class hopefully). Thanks in advance for input. Ide like definite answers but if ur pretty please tell me wat you know.
