Are any of these housings interchangeable?

RR Classic vs P38

DI vs Defender

Series I vs II vs IIA vs III

I'm working on a project and don't want to duplicate housings if I don't need to, and wanted to know what can be substituted where. That clear enough? :p

No

DI vs Defender

Yes

Series I vs II vs IIA vs III

Don't know.

Series I vs II vs IIA vs III

SII, IIA, III are all interchangeable, however, SI can be tricky, as most are narrower. Also Airportable axles are narrower, however, all use pretty much the same 3rd member.

Thanks for the info so far.

However, I guess I should have been more clear. Are the mounting dimensions the same?

You mean, for the leafers are the spring perches mounted in the same spot?
If so then yes...... sort of
II, IIa, and II all ahve the same perches on the front. Rear 88s are all the same and rear 109s are all the same.

For the Disco I, RRC, and Defender yes for every coil axle I have seen. Never seen an airbag axle so not sure what the mounts look like..

Air suspended vehicles are identical, except for the shock mount ahead of the axle-in the front.

Thanks guys. That's a big help. :beer:
