Two steps forward and one step back . . . Thanks, Dr. David - as it turns out, the washers included with the transaxles are not high collar; they are significantly larger outside diameter than the head of the socket head bolts. However, the correct washers arrived today with the longer bolts...

Alex - thanks for the tip. I checked and sure enough, if I use the supplied lockwashers, the bolts are about 5 mm too short on the transaxle side and about 2 mm too short on the wheel side. By "too short", I mean that the bolt does not go all the way through the threaded part. This is not...

I just opened up the driveaxle box to take measurements for the bolt sizes and what should I discover, but a bag of bolts! (duh). So, for future reference if anyone needs them, each driveaxle requires: 12 M10x1.5 X 55mm grade 12.9 socket head. In addition, there is a label on the...

Can anyone offer the specs for the Graziano axle bolts? (inboard and outboard)? I'm guessing these should be at least grade 10.9?

The coolant lines have now been tacked-up and are ready to go out for finish welding. This was actually kind of a fun job. Using a chop saw and a belt sander helped it go more quickly. The chop saw made quick work of the cuts and the belt sander helped clean the ends after cutting. Various...

My welder says tacking without back-gassing is fine. I'm about to start tacking pipes together, but someone pointed out that running solid pipes up to within a few inches of the engine and radiator will make a long piece that is not very flexible, making it susceptible to potential fatigue...

I know red loctite is considered to be "permanent", but bolts with red on them can still be removed. In another application, I removed bearings which had loctite on them without too much difficulty (I think it was red, but not positive). It may be more effective when contained within a thread as...

The replacement pilot bearing arrived (thanks, RCR!) and has now been installed in the flywheel using red, high temperature loctite. The bearing was a pressure fit and was installed by tapping lightly around the edges with a hammer, followed by a large socket that fit onto the outer race. The...

I removed the unneeded pilot bearing that came with the LS7 crate engine. As it turned out, this did require removing the flywheel. In addition, the old bearing was held in place with loctite. I used one of these to get it out: 3-Jaw Pilot Bearing Puller and it worked, but not very well, as...

I have been doing all my threaded holes with these: Greenlee DTAPKIT 6-32 to 1/4-20 6-Piece Combination Drill and Tap Set - Amazon.com Very quick and haven't broken one yet.

Makes perfect sense to me! Assuming these are already the shortest bolt that keeps the shank under the loaded areas, the only option to go shorter would be to cut them down, which would mean the cut ends would be unplated and exposed to corrosion . . . think I'll just leave well enough alone.

There are a number of bolts on my car that appear to be longer than optimal. For example, in the attached picture, I am thinking of replacing the two wishbone bolts with ones which are shorter and installed in the opposite direction - as it is, removing the bolts requires removing the shock...

The Condenser lines are moderately small and will fit through the holes in the radiator with room to spare as long as you don't have the hose ends installed already.

Mahlon, You are ahead of me on this. I have not tried to connect the cables yet, but will be watching to see what you find as you blaze the trail!

Thanks for all the info! I will check with my welder before tacking anything up to see what method he prefers.

Thanks for the tips on Columbia - I was searching online for a good supplier and otherwise coming up empty. What is "back-gassed" and is it needed for just tack-welding?

I'm glad to find this out now and not after starting the engine! Yes, I have the LS7 engine. Should the stock bearing in the end of the crank be removed or does it serve some other purpose that I would want to keep it there? Now that the flywheel is already mounted on the engine, can the...

I was quoted $1,500. As an alternative, I have a MIG welder, but am not very good at it. I might get a roll of stainless wire and tack weld the pipes on the car and then take them to someone who knows what they are doing for the final welding.

Oh, boy. Maybe I did make a silly mistake? If you look at picture #2 from post #85, you can see the pilot bearing installed in the end of the crank. The flywheel fits over the end of the crank and has a larger inside diameter. You can see it in picture #3. If the pilot bearing is...

Now that the engine is back in with the modified water pump, I am able to measure the distance between the RCR-supplied straight solid coolant line running down the side of the car, and the water pump. On the driver's side, the distance is a little over 48". I was originally thinking I would run...
