Classic Dampers - Early Range Rover

Hi all
Does anyone know where I can find part numbers for early RR shock absorbers?

Retailers seem to be listing RR Defender and Discovery shocks under one part number, which can't be right. I feel sure an early RR will have significantly softer shocks than a defender....

I am looking to buy standard shocks, not gas pressurised or uprated.

Kind regards

Good place for part numbers, can look for cheaper elsewhere

What year is your RRC?
I have a 70's parts book knocking around somewhere & I'll see if I can dig it out.
You're likely to find the old part numbers have been superseded over the years.

According to the1970s parts book:
Front RTC4582
Rear RTC4583

1977 parts book.

Numbers have been superseded many times over the intervening years.
According to the Brit-car site 577652 is now STC3941 and 90577392 is now STC2829. If you look at their site it shows a lot of numbers by each part incl those posted by Marshall.
