Driveshaft removal for speedo gear swap. C-Beam out or not? - ZR-1 Net Registry Forums

scorp508 · 3 Weeks Ago

My 94 still has the stock speedometer/vss gear in the transmission even though the D44 has 4.10 gears installed. I have the 13/43 gear from Haibeck to install but wanted to ask a quick question.

His instructions are here: http://www.zr1specialist.com/HAT%20W...on%20Gears.htm

It goes right from remove the exhaust to remove the driveshaft. Is there enough tunnel space to remove the U-Joint strap bolts and get the driveshaft out without also removing the C-Beam? There really isn't in enough room in my '87, but that is an L98 and DN4+3 setup which may be a little different back there.

If I have to remove it that's fine, just curious what to expect. Thank you.
