engine and drivetrain Almost Done W/ The 5 Speed Conversion, Help

[king02]

So I have a 70 2002 4spd, doing the conversion, motor in, tranny in, 3.91 rear et al done too. My problem is that the drive shaft and 5 speed were in another car, I purchased it for my conversion. And upon putting in the driveshaft and guibo...IT IS TIGHT. TOO tight i believe. ANY SUGGESTIONS! One suggestion was to grind the guibo metal guides 1/16 on both sides to give an 1/8 of an inch. How much slack or play should  I expect.  Appreciate any feed back.

any chance to loosen the diff and slide it back?

My conversion mated up precisely at the Guibo, no gap, no pre-load.

_{before grinding the guibo, i'd check the axial position of the engine within the engine bay.  ditto on the differential.  there's about an inch of forwar/aft movement on the differential.  maybe your engine can move forward a bit.  if the fan is not hitting the radiator, that is...}

As they said, loosen the six differential bolts. Slide the diff back in the carrier. Mate up the guibo to the flange. Tap the differential forward with a hammer and a wooden block and tighten the bolts. Do the guibo-to-transmission-flange-alignment thing as per my recent blog post.

Touche', much better after loosening the differential bolts. Preliminary run upto 40 mph...thats pretty good since she had been dormant for 4 years or so!  Thanks for the three O2 amigos. Need a couple of shake down runs, any suggestions to cleaning downdraft 38s or additive to fuel (93 leaded..the real stuff), hoping the carb will clean as i drive.
