Oh, Mighty Vanagon List!

I have removed the H&R lowing springs from my recently acquired 85
Transporter and discovered that they don't look like or have the same part
numbers as the H&R "Sport Springs" that I have seen FS around the web.  The
H&R Sport Springs I've been able to look at on various web sites are red in
color and are part number 29951. For examples see

Mine are green and have part numbers 100 22 100 VA on the front springs
(11-3/4" tall) and 100 22 101 UH on the rears (8-5/8" tall).  Both fronts
and rears also have 5/2001 written on them next to the H&R brand name.  I
can e-mail a photo of my springs that clearly show this information.

I Googled the part numbers on my springs and came up with a German language
match.  http://www.auto-exclusiv.de/Tuning/H_R/Cup-Kit_Fahrwerke/VW/vw.html
This web site may have some information but doesn't help me as I don't
understand German.

It's possible that they are the same and just a different color but I would
like to sell these springs at some point and would like to know more about
what I'm offering; more than that they make a Transporter single cab ride
about 2" lower and hug the curves nicely!

Can anyone offer any insight?

Thanks,

Andrew
