NOS Rat transmission
Someone wants to give me a NOS RAT early Bronco transmission. I have a well worn RAN in my 68 now. Is this a direct bolt in.? I know the length is 3/8 longer but what else am i going to run into?

I went and picked it up It is NOT NOS. but a very clean hardly used rat and intermediate housing. ( what the heck, it was free) It was out of a 74 and is very nice. The 64$ ? Is will it fit in the place of my RAN. I notice the intermediate housing is shorter but the trans is longer than the RAN set up. They seem to measure out the same. Once all connected. I guess if the D20 will mate to it then it is all a go??? Any suggestions appreciated.

RAN and RAT chart.
Input length would be a question, mounting the TC to it another.

The tag matches the CE2 designation which appears to be for 302. Even though my truck has 289 badges on it. It has a 302 block with 289 heads from factory. Rebuilt the engine last winter.

RAT v RAN seem to B about 'out put' rather than much else (tq differences of v8 & i6) and the length (v8 shorter). Both R good to 500HP. I'd "make it work" for free.
They get 3 & 4 hundred dollars for that simple 6 inch tail piece offa the RAN.
Guys here use it 4 their tube chassy circle track racers (400 HP che**ys) as they only weigh 100 #. Just use 1st'n 3rd I imagine.

trans swap
never saw the bent8.
The distance frm that rear flange to 'bell interface' is where it would B different, no? My i6 has a 6 inch intermediate I believe the
bent8 doesn't. Don't the motors get mounted further ahead or back in the frame w/8 v 6 (due to this length difference). IDK -
Clack?
85F150?
Y not measure under the vehicle (space frm bell to transfer) U got now & compare to the transmish U got layin on da ground?
(I thought u'd go C6/C4?)

Would love a c-4. But free is free. And the one i picked up yesterday has like no use on it. Clean and grease free. Owner told me he pulled it and did a 435 swap decades ago. Then sold the truck . He has a custom 74 with a 351 EFI on c-4now.The dash had to cost him 8 grand due to the custom work for A/C and stereo gages. Power everything......and he hardly drives it. Think the last time he took it out was last September. But, i would be afraid to even scratch due to the paint job on it.

The suffix is very important, because RAT's were also used in F100/250's, Econolines and Passenger Cars.

Yes it is a CE2. I have all the parts spread out now. So i am looking at 2 RAT intermediate housings and 1 RAN housing. 2 rats tranny and 1 ran tranny. I think this is going to work as the measurements seems to be working out. The intermediate shafts all seem to be the same length.....how can this be??? Also all the tranny output shafts are measuring out to be the same. ???

"...how can this be?..."
C my above posts,
easier to make components same & move PLACEMENT
than to make multiple components, I'd imagine.
The intermediate is there to take up difference.

Parts are parts....and i have a lot to play with. Decided to since i was this far torn down to do flywheel re-surface and go ahead with a new clutch even though the old one is less than 2 yrs old. ( ounce of prevention)
