Flexplate to crank bolts--- A4 flexplate bolt (m10x1.5x23-g) (need 3) (98-00 LS1) = 12560397

Stall to flexplate bolts--- 12mm x 1.5 the length is 20mm (this was with a TCI flexplate though and not the stock one...you may need shorter ones)

Bellhousing bolts--- M10x1.5 - couldn't find the length

Crank sensor bolt
Cam sensor bolt
coolant crossover bolts

You also need motor mount bolts
