Staight axle, shock ???

[Trucknut57]

I need some help with shocks.

Here is what I've got: 1957 chevy 3200, original straight axle, stock leaf springs with a couple leafs removed, power rack & pinion steering, SBC engine. Camaro rear axle with TCI leaf spring kit. Distance between upper and lower shock mounts as it sits now is: front- 11", rear-14".

On to my question:

What would be a good shock, at a fair price? I'm not looking for shocks that are $100 a each, I use this truck to pull a 6'x10' trailer, sometimes.

So far my biggest problem is finding shocks that have enough travel.

Any suggestions would be great.

Thanks.
