... I just joined & I've been checking this General Discussion 1st . But now that I'm getting my feet on the ground somewhat. I'm not finding the information that I'm really looking for. SO Is there another section that I should be going to for my information. What I need is answers to questions for swapping the very 1st 6BT FROM IT'S 1989 FRAME INTO my 1988 D250 GAS TRUCK . My 88 is a low mileage truck .. I need a location that'll know What IS THE DIFFERENCE IN THE 1988 Gas 727 trans & The 1989 Diesel 727 .. WHAT do I need to move from one truck to the next . Some have said the COMPUTER WANT MOVE OVER. I'm not sure about the Computer . ?. I think my trucks are old enough it wont matter. But I've wondered about the RADIATOR CORE SUPPORT .. & i REMEMBER The very 1st diesel Pick-ups had to be recalled & something was done to the frames . So My 88 FRAME MIGHT NEED SOMETHING . I don't believe I;ll do anything to mine I'll just wait for issues .. If I get this swap done . Farm use I'll not put 7500 mile on it before my Demize . I'm 70 already But I'd sure love to convert My 1988 into The very 1st 89 diesel motor .. ...Thanks .
