driveshaft shortening

I've had driveshafts shortened before but it's been 20 years. IIRC it was around $100 back then. I just got a quote from a local powertrain shop and they want $200 plus joints.(non greasable Spicer) That's new driveshaft territory. If I go new, is the tapered end a requirement for clearance?(pinion snubber?) I see some shops offer custom length shafts but their shafts aren't tapered.
