I have MTD Nickels on both my 55-02 5-string and my 6 string. Both are 35" and strung through the body. They are fantastic strings as well. Comfortable, great tension and amazing sound.
They are available with either a .130 or a .135 B string, both tapered.
I think D'addario makes Extra Long Scales as well that will fit.
I'd say give a DR set a try. All of their sets are 37" in length, so you'd be set.
Personally, I love their Sunbeams the best, but all of their string types/sets are top notch!

It depends on how far past the bridge the strings go before they enter the body, (and how far they go beyond the nut to the tuners), but you should be good with any set of strings that are labelled "extra long scale" or "super long scale."
You might get away with the "long scale" sets, but you'd want to get measurements of the strings' lengths vs. the length required on your Peavey (as well as where the taper starts). It sucks when you get a set of strings that are short enough that their end-taper starts right where it sits in the nut slot.
DR longnecks are perfect for 35" through body actually given the length of the taper I would say they are made for these types of basses. Only problem I've had from them is the G string breaks without fail on every set after 6 or 7 months.
String length (or string recommendations for 35" through body)
