Savage 77 A, B, C, D, ?

I recently picked up a sweet little Savage 77C with an 18" barrel and an overall length of 38" from stock to end of the "Savage Adjustable Choke". (okay, not the most iconic gun, but the price was right, and it's in NICE shape)
My two questions; 1) Does anyone know if the parts are interchangeable with other 77 models such as A, B, and D?
2) Other than the Coast to Coast Model 267, are there other guns that can interchange parts with the 77C?
Thanks in Advance for any info

 

I looked thru the Numrich listing and it seems that many parts are the same for 77, 77A, 77B and 77C. Most of the ones I looked at are available but only a few were listed as 77D compatible I didn't check their crossover list to see what other brands are the same..

 

Thanx! I'll take any other available info anyone may have as well.
