I have a question about the two service manuals available for the TGP:



I already have the manual on the left, but what does the manual on the right contain that the other one doesn't?  I've found that my 89/90 update doesn't contain a whole lot of info.

Thanks

It has the TGP specific stuff and it would be a good idea to get the regualr GM 1990 GP manual also which has the rest

No I know that, but what does the manual on the right contain over the one on the left?  The one on the left is an update, and the one on the right is a supplement.  What is the difference??

I have them both, but they're not in front of me. The supplement is like 5X thicker than the update. For the $20 they go for on ebay, its a worthwhile buy just to say you have it.

I just bought the above set for $6.  :icon_cool:  So I will have both very shortly.
