Hi all.. new to the site but see a lot of experience being shared here.. hoping i can impose from time to time.

I am gearing up for a complete restoration of a 1970 360 RT1 that Ive held onto since High School.. The bike has been in dry storage, dry climate.. 

As Im doing the takedown i am sorta shopping  for parts. 

Regarding part numbers in my Parts and Service manual 70-71, many part numbers are still available as the book is calling out.. 

I read a article here written by administrator that laid out a lot of info..

First 3 numbers, first year used.. ie:214 / 1970

Next 5 are the part id.. prefaced by a W if memory serves referencing a group..  ive not seen that yet

Next 2 a revision.. 

My question to the experts concerns interchangeable parts through models and years. 

For example:

My manual calls out a lighting coil (2) / stator plate
275-81314-20

Is a 233-81314-20 the same application/part .. just a earlier year and would it work if that part was needed. 

Id appreciate any incite. 

Cheers,

Drac
