Can't find correct length rear shocks

Hey guys, got a 69 C10 with a coil rear end dropped 4/6. I'm running the hotchkis springs which have a pretty light spring rate in the rear. Rear shocks were at a pretty nasty angle so did lakeroadsters rear upper shock relocater which I'm happy with angle wise. I've attached his link so you can see what I'm working with and in case it helps anyone else out. Easy, well thought out, and works. Thanks lakeroadster

Now it's time to find some new shocks since the old ones are seized (probably from the angle they were run at) and the incorrect length. I've looked up how to measure and I get 9" compressed, 13" static, and damn near 18" with the wheel just barely touching the ground extended. The po did some funky stuff but don't think he did a long travel rear end. Nonetheless I'm having some trouble finding a shock that meets those lengths or anything close.

The truck was lowered 7.5 out back so I notched it. I figure I can limit the downward travel with a bigger bumpstop but the notch was a pia and I'd hate for it to be for nothing. And while I don't plan on necessarily jumping the truck, I do want to beat on it, and don't know if using the shock as a suspension limiter is the best idea.

I've been looking through manf. pdfs at lengths and I'm lost. I know I'm not gunna find a shock that's 9" compressed with a 9" stroke but if you guys can point me in the right direction it'd be greatly appreciated.

Re: Can't find correct length rear shocks

You cant go by the length with the rear hanging with out the shocks as the shocks a lot of times is what is holding the rear end when you jack one up. I would take your 13" static and ad 3 inches of travel and look for a shock.

Re: Can't find correct length rear shocks

That's about the dimensions of a front shock for your truck.

Building a small, high rpm engine with the perfect bore, stroke and rod ratio is very impressive.
It's like a highly skilled Morrocan sword fighter with a Damascus Steel Scimitar.....

Cubic inches is like Indiana Jones with a cheap pistol.

Re: Can't find correct length rear shocks

You notched it enough that you have 4" of uptravel? That's more than I'd have expected.

I agree that you won't be able to get that much droop either. If you look at a single telescoping shock with ends for attaching to something, you can't have extended length double compressed length. I think a couple inches of downtravel would easily be adequate.

Re: Can't find correct length rear shocks

SCOTI that made me check out front lengths and summit has some edelbrock ias's for just $20. Think at that price I'm gunna go for it. Just wondering if shocks at that price point are valved or tuned differently for front and rear? Guessing if they are they'd be way to firm. Or is it likely the same shock in a different length?

I agree on the valving concern when utilizing front shocks in a rear application but I know guys have done it. Me personally? I always try to stick w/the correct shocks & move the mounts as needed to get them to work. If I can't tweak the mount locations, I'll seek out the closest possible application w/the correct shock ends & length required (I used Monte Carlo SS/g-body shocks for the rear of my 90).
