GM Lube Okay, I' m planning on using GM Lube and posi additive in my 68'. I have seen numerous versions and part # for these products. For the Diff lube theres AC Delco 80W-90W 10-451 GL-5, AC Delco "speacial formula"75W-90W 10-4061, Genuine GM Fluid 80W-90W GL-5 89021669, or AC Delco...

Well it turned out to be an upper PB spring that dropped down to the bottom of the PB area rubbing not a wheel bearing as was thought. While I'm undertaking the PB repair I have a clear view of the rear diff. plug. The car has never had a fluid change. Wondering if its a good time to drain...

Looks like the trailing arm is a bit tricky to get off. Anyone ever tried this?

Just pulled right rear wheel off and noticed fine metal flecks on inside of wheel and along trailing arm etc. have been noticing a rubbing ,scraping sound coming from the rear of car lately. Bearing problem? any other possibilities? Assuming its a wheel bearing is it a difficult do it yourself...

mission accomplished. thanks for the advice. manged to get it off and on with luck and per:happyanim:sistence.

thats the problem. The bolt goes through the crossmember of the chassis where the upper bolt sits in an indented part of the frame then it passes through the carrier bracket where the lower nut is The upper bolt cant be seen so I need to squeeze my hand between the the carrier bracket and the...

Okay, I have the new rear differential carrier to chassis bushing set. This is no where as easy as expected. to remove the old bolt that secures the bushings I sprayed the old bolt good with PB blaster no luck. I cant get the bolt loose it just spins and there does not seem to be any wrench that...

I have only been seeing poly replacements for these bushings. Why do you suggest not using poly and where can I find none poly bushings?

thanks for the suggestions. my u joints are sealed units with no grease fittings. I'll try the Diff. cushions first.

I have noticed an occasional rear end clunk when shifting gears, particularly 1st to 2nd especially if I let the clutch out quickly. If I ease out the clutch it helps eliminate the clunk. Sounds like its right rear but cant tell for sure. Thought it might behalf shaft U joints but I have read...

I need a coil for my 68 327/350. The coil in now is a chrome accel but its years old with no defining information on it. I see that after market coils have all types of Ohm ratings. i have seen .6 up to 1.5 primary resistance ratings on aftermarket coils. Looking at my shop manual I see a rating...

I am in the process of restoration. I will be driving it around for pleasure. No racing is planned though some nice handling potential is desired. I have an old pair on this car thats rusted and probably 30 years old at least. They may be still fine (cars been in storage for years) but while I...

I am planning on replacing my shocks on my 68' starting with the rear. Any suggestions on brand/type etc. I cant spend the big bucks so I'm looking for a good quality shock that will last without braking the bank.

thank you

Just pulled the plug to check rear posi fluid levels. When I ran the bolt back in after checking I noticed that the plastic posi traction warning tag that collars the bolt moves freely. The bolt is in as tight as I can get it and it went in smoothly without misthreading. Anyone know if this is...

Thanks for the information!

Not yet. The car has not been run in many years and I am in the process of replacing all old hoses and belts etc. before the start up. I have hunted around but cant find any belts that are slightly smaller so i guess I'll have to go with the looser belt and hope it works out.

I just put on a new water pump belt. My old brittle one from 20 years ago that i just pulled off has a Gate # of 7325 which Gate tells me they have the same belt # now as well (and is listed as the replacement # for the original GM part). I measure both belts and they are very close but the...
