frame length question

[Caman96]

basically I'm doing a sas with a 4 link front and I'm going to use the stock 2wd spring pockets I have dana 60 front with spring pockets the perfect width already installed so all I need it radius arms or in my case a 4 link. But since use my truck(as a truck) a lot my idea was to get a frame to build the suspension on and swap my body over when that's done to limit down time. But I was hoping other frames would work because no one in my area has a single cab long bed frame but there are a few extended cab and crew cab short bed frames.

Nothing on FB MarketPlace? Either wait or travel.
