Pretty hard to make any kind of direct part # recommendation without some idea of what will fit in there, but basically you would be looking at 125-140 lbs seat with 300-340 lbs open. You're going to have to get in there with a pair of calipers and at least get a diameter and use the depth finder on the caliper to get a decent idea of installed height.

You can get a functional digital 6" caliper off Ebay for as low as $12 or so, I paid $16 for a 10" that I carry in the truck just for general use when I'm out and about helping friends or at a swap meet. They may not be totally accurate to the .001" like an expensive one, but if it is within .002"-005" it's close enough for this type of work.

Howards Cams/Competition Products at www.competitionproducts.com has a very good selection of valvesprings at real good prices, you should take a look there.
