Using a BW 1350 OR 1354 behind an M5OD ?'s....

[B2 Addict]

Ok, unless I'm wrong, I have determined I can use an M5OD transmission with a 4.0 clutch set up behind a 2.8.......my 1st question is, can I use the BW 1350m behind an M5OD or do I have to go to a BW 1354m? My 2nd question, if I have to use the 1354, are there any driveshaft mods that would need to be done? Any more info I may need would be appreciated! I currently have an FM 145 with a 1350m...........

The M5OD is the same length as your FM. And the 1350 will bolt right up. No changes need to be made.

Thanks man, I'm learning slowly but surely!

The FM 145 is shorter then the M5OD (2.5" IIRC). (driveshaft mods will be needed, or swap in shafts from a FM146/13-50 truck.)
The FM 145 and the M5OD use different T-case shifters.
The shift arm on the 13-50, used behind the fm145, may be different then the one used with the M5OD shifter.

Disciple was right about one thing, it will bolt up.

I'm sorry. I thought the 145 and 146 were also the same. My mistake.

If you do use a 1354, the front driveshaft (1354 specific) will work just fine with the D28 (the 1354 only came in D35 rigs but has plenty of slip yoke to work with a D28) and will also be perfect if/when you do a D35 swap. Rear is the same between the 1350/54 except later 1354s which had a large pattern rear output flange, and other than FX4s, I'm not sure there's any manual 1354s that late anyways.

Thanks man, I guess I'm just gonna have to replace my busted up FM 145 and keep my 1350, that way I don't have to modify anything as of yet. I do plan on a D35 up front to match the 8.8 I already have installed, but it will probably be a while due to lack of funds.......

I just need to get my B2 back on the road for now, when I can afford it I am gonna to find me another 145 and do the 4.0 clutch setup, I think it will be sufficient for what I want to do.........Thanks again for the info!

No sweat bro, I'm still trying to learn all the differences and set ups I will be able to use at some point and all the info I can get is a big help!

I'd like to come up and grab one of those low priced FM 145's but I'm fighting to live financially right now and just can't spare a day to come pull one....I'm kind of between a rock and a hard place.....

You will need to change the infernal little lever on the t-case too, and since it is usually not removable on the earlier trucks you might end up needing a different t-case anyway. If it is removable there are tons of A4LD trucks and later 5-speeds (I can never keep them straight) with the longer lever that you can swap. 85' was right around when the switchover started.

I think I just found a removable lever to go the other way for my C5... which was kind of tricky. And don't think you can change the length of them, in addition to being a really odd fraction they are also clocked differently. I will update my posted thread tomorrow after the paint dries on the new lever.
