Hi, if the front shocks fit all those models , the only variations I can recall are bottom shock mounts with holes and some with slots ? also larger diameter ( more oil inside I suppose ? ) I can remember having to grind out control arms to fit these larger diameter shocks into something Holden ?? Hope this Helps a bit ....Mark.

I've got a set of shocks that came out of a HK Brougham front end with the part number 2806490 which doesn't appear in HK or HG parts catalogue. when I googled the part number i came across an old post from Holden general discussion from 9 years ago and the same shocks were in a HK Monaro, doesn't say V8 or 6. post was HK(tg)Monaro shock absorber query and the result was the number is for housing only not complete assembly.don't know if these are close to what you are after but the markings go like this.

tried measuring extended and closed but came up with totally different numbers than you wrote. where do you measure from. I measured from centre of top rubbers to mounting plate at bottom. measurements are closed 295mm, extended 383. both shocks have same date nos.

I got a exchange lower control arm from Pedders about ten years ago. When I fitted it (WB ute) the hole in the bottom was too small to fit the shock. There must have been more than one shock for HQ to WB.

You amaze me HK, and others here of course...I'll go check through my lot of old shocks ....the rubbers are most likely stuffed though..The new after market stuff is better than those old ones or are you just after originality?

Who do you use to re valve shocks ?? I have some original spiral type shocks for my hk that i want to re valve. cheers

These arent the number you're looking for but were GT130's painted metallic gold in the 80's?
My neighbour worked at Monroes in the 70's and he reckons these are GT130's but I dont know.

Front part# 146 (Date April 1986)
Rear part# 052 (Date April 1986)

The old original Monro Wylie GT 130 shocks were better than the Monro GT 130's, as they had the twisting bore look and were valved different to the Monro GT 130.

I remember they still were oil but no spiral and valving was not as good and quality was not as good, the gas type did come out as well, but I don't think they were as good as the old spiral Wylie.

I remember being pissed off about the new type GT130 when the old ones were better, just that the bottom rubber O ring had flogged out on one of the GT 130 Wylie, so I changed them.
The gas ones were no better than the oil, in fact they felt were softer than the oil, back in around 1985 I think it was.

My front shocks are also Wylie shocks with the GMH symbol on them

Hello Byron and all.

I finally went to the shed and found the shox in box...Pardon the pun.

So Byron, I think these are the ones you are referring to as just being thrown into boxes. When I bought them I thought someone had bought some GMH ones and possibly did a switcheroo, returning them to a dealer for refund. Mind you back in the day people would buy something aftermarket as it was known that factory suspension was pretty basic.

Here are some pics: Sorry, I could note rotate them on Tinypic.
