Dresi,
The few parts I have bought for mine I got at Sew Classic and Sewing Machine Parts Online. Some parts can be found under other generic parts. You have to do a bit of searching as some parts have different numbers. This group as well as the Yahoo Kenmore group are great for help and info. I have found very little info on the TriSpan 88s. Ebay is a good place to search. Good luck with your search and sewing.
