Removing a bogie from the axle...

Re your P.M.
Universal carriers have front springs and rear springs.
Front outers;
10 1/2 coils, 10.22 to 10.42" long. TL332
Front inners;
13 1/4 coils, 9.09 to 9.19" long TL331

Rear outers;
9 3/4 coils, 9.4 to 9.6" long TL126
Rear inners are the same as front inners.

The part numbers are often stamped at the ends of the spring.

Alistair I have some (as previously mentioned) longer lighter outer springs that I thought were Loyd springs.
I have also taken longer, lighter inners from U.C. suspensions. I am keen to have you list the specs of the Loyd springs eg TL 1386 which is probably a Loyd part.
