Oil; seal will be the easiest and cheapest part to buy.

Was a little hesitant about pulling the rear seal out till i asked the question. Some parts are hard or no longer available, Couldn't buy a new set of points or condenser for the 281, but found Ford ones would work with minor adjustments.
Had a rat through the glove box in the parts D series, was just like Christmas 2 new sets of points,1 new condenser, 1 fuel pump rebuild kit, rota button, dizzy cap, globes and fuses, the previous owner was prepared for all occasions.

You have a T15A transmission ,4 speed.........and note,in no way is any Dodge gearbox interchangeable with any IH gearbox.............yes,the Dodge NP boxes do have a majority of parts the same ,but not the casing or the clutch splined shaft......Ford also used both boxes over the years,again ,boxes are not intechangeable,but many parts are..............If you decide to pull your box apart,they are a bit tricky......you have to drop the layshaft,and pull the mainshaft,then pull the clutch gear ......to reasemble the box,you will need a slave layshaft to keep the needle rollers in place.

Sounds similar to the M21 4 speed...

Would it be advisable while its in bits, mostly in bits to put a new input shaft seal in as well
Dunno nothing about these gear boxes at all but have found that in old rubbish I own that hasnt run in a long time the seals usually fail not long after the fun of driving begins

It is pretty easy to change these things now than when it is all back together

Yes your correct. The front seal is in the bearing retainer and have tried to get a seal it,s a secondary type seal ? as it has a drain back hole in the gear box housing. would have liked to have change it but all it got was a lube up with good Castrol grease...

Good that your spark is sorted. I have not bought or used a condensor now for many years. Instead I buy and use film capacitors, cheaper to buy and far more reliable.
With a good condensor or capacitor your points will last for many years. That is the part that can cause erosion of the surfaces of the points along with wrong gap and suspect coil.
