69 COPO Camaro Coil Spring.......code #'s ????????

[CamarosRus]

RICK's catalog does not show a HQ spring..........

With ALL the COPO knowledge at this web site, does not someone have knowledge of correct spring code and/or who sells the correct part.........

Thanks

Chuck, my 69 20K mile L-78 Camaro had YP code springs and a perfect ride height. I still have them with the original tags. I would think the ride height would be the same for a 427 COPO as the engine is outfitted basically the same. Do you have any 2nd gen parts to trade????

Ride height with YP front springs.

YP springs in Rick's Chart show 181-262 added weight.
I obviously dont understand these charts.

Chart in RICK's catalog (page 69) shows
L-34 add 209 lbs
L-78 add 133 lbs
other than intake where is diff between L-34 and L-78 ???
M-40 add 44 lbs
J-50 add 9 lbs Power Brakes
N-40 add 40 lbs Power Steering
T-60 add 6 lbs HD Battery
V-01 add 7 lbs HD Radiator

I repeat my above X-11 "COPO" has Headers, No Smog, but otherwise very similar top a REAL COPO!!!!!!!!!!

Paul, Curious why you changed springs in your (sold) L-78 if you were happy with height/look?????

I would be willing to buy/trade BUT I need to know I will be happy. I am tired of spending money on parts and labor..

Also my car has cowl hood, not SS hood (weight ????)

[Hotrodpaul]

I went to L-89 Aluminum heads and found the proper NOS YM code springs on ebay. The heads took about 80-90 pounds off the front end. I would think the SS hood and cowl hood would be approximately the same weight.

Chuck,
You have an interesting way of asking for help.

Paul,

That ride height is sweet - and perfect!

Now I'm confused though. You mentioned YP springs on this
car, then you mentioned L/89 heads later..... Did I miss
something? Does this Camaro have iron, or aluminum heads?
And what about those NOS springs? Are they in this car now?

You know, this issue has been debated numerous times here.

I looked at that front coil spring calculator last year,
but it seemed that there were so many variables to consider.

Does anyone here know, or have a reference chart regarding
all the front coil springs that were made for the '69 Camaro?
Do any members here have original springs that they
can use to verify tag codes?

I would assume that for big block, there are the determining
factors:

1 - L/35 and L/35
2 - Muncie or THM400
3 - L/78 or L/89
4 - A/C ( L/34 & L/35 only )
5 - 3 or 4-core radiator
6 - hardtop or convertible

As all BB Camaro's had SMOG and cast iron exhaust manifolds,
that can't be a factor. Nor can power brakes as that was
mandated. Would P/S add significant weight to require a
different spring pressure?

Can springs be clipped to reduce the ride height to a "desired"
height? If so, is there a formula ( other than try-it )?
Lastly, what exactly is the proper ride height? Paul's
Blue SS looks perfect to me. Got a ride height for us Paul?

One more thought for the moderators. Perhaps we should start
a "sticky thread" for front coil springs. It sure would be
helpful to know what others owners have used for their
particular applications, and where they got their particular
springs.

Can unsprung height be used as a determining factor for used
springs? I know that when I source new springs for a particular
manufacturing project, unsprung height is a factor. Any thoughts
