what do i got ?

hi fellas, i got my chance to buy a 1978 bronco, the current owner doesn't know anything about it, so i'll ask ya'll, it doesn't have a motor but it's got manual tranny (don't know the speed), transfer case and front coil springs. so what kind of tranny, transfer case and type of differentials will i be getting ? i know this is very vague info but thanks for the help. i am really interested in what type differentials and ratios, thanks again

Re: what do i got ?

You're right; that's vague! The rear end is almost certainly the venerable Ford 9-inch. The front is probably a solid Dana 44. The ratios should be stamped into a thin metal tag held on by a diff. bolt on each axle. NP435 4-speed transmissions were common in that era, but I'm not sure about the T-case.

83 Custom w/95 4.9L EFI, 78 NP435, 83 NP208, 83 D44IFS 3.07, 87 Ford 8.8ABS 3.08, Michelin LTX AT 31x10.50R15

Re: what do i got ?

The brakes are okay...you can cross drill em to help them cool more efficiently....9" is good, the 44 questionable, since u have the straight axle, a straight axle conversion can be had more easily compared to us ttb guyz. A 60 conversion could be had for you in a matter of hrs, if the gears are the same, and I can't hold back my jealosy for the ease of installation.

Re: what do i got ?

the '78 came with only a 351M or 400M from the factory. the block is the same(bell housing bolt pattern, accessories, etc. If the trans is original it's a 4 speed. if you have manual locking hubs, then the t/case is a new process 205. The front axle is a dana 44, the rear is a ford 9 inch. the most common factory gear ratio was 3.50. the 429/460 big block has the same bell housing bolt pattern and they make aftermarket motor mount conversion kits for an easy swap. my '78 has a 460.
