Late model 26 spline Muncie M20 4speed gearbox from Corvette 74'

Late model Muncie M20 4speed gearbox with 26 spline input shaft, drain plug and big 1" countershaft pin. Basically swap the gear set to M22 and you have the "rock crusher". To mate with ls engines you need Chevy Big Block p.n. 621 bell housing and any 26 spline ls1 ls2 ls3 or ls7 klutch kit. The gearbox came out from 74' C3 Corvette. I never had a chance to run it but it shifts and turns smoothly.

Ask me about shipping.
