[Spridgets] Bugeye / Midget conversion parts

[Miniac7 at aol.com]

I'm switching from front drums on my Bugeye, to Midget discs. In doing so,  
I'd like to get an opinion on which coil springs to use. I noticed that the 
 various supplier catalogs show different part numbers between the two 
cars. Not  knowing what the difference is between the two variations, I'd like 
to know if I  should I stick with the Bugeye coils or switch to the Midget 
coils? I have both  on hand. This is for a road going car. A pair of Peter's 
reconditioned shocks  are going in at the same time.
 
Also, I have a similar question regarding the rear axle shafts. While  in 
the process of switching from the Bugeye diff gears to the Midget diff gears, 
 should I use the Midget axles or stay with the ones from the Bugeye?
 
Thanks,
