Any chance I can use the yolk outta my D27 in the D30? Just wonderin' Otherwise I getta figgure out a new driveshaft. I'm kinda worried about it because the small front driveshaft ('68 V6 CJ Donor) would kiss the starter on full flex - I'm afraid a bigger one is gonna compound the problem. I will have more travel though, so I can just go to lower bumpstops. Thanks for any words of wisdom.
