Im thinking of bolting a toploader behind my Y block and was woundering if a toploader 4 spd would bolt to the t-98 belhousing?

Car and truck bells are sometimes diff depth. Input shaft length important too. Also, pattern on bell. Toploader may have both patterns iirc, see some pics here:

I'm thinking the input on the t98 might be 6 1/2"????
