in trying to locate an adapter that will allow me to bolt an 86-91 bell housing to a gm T56 gearbox

i did a search and found a few threads related to the topic, but none seemed to indicate where one was available.

i did find the link to a t5 adapter, however i dont want to use a t5


im not quite sure why this isn't a more popular topic. when the standard gearbox's really are quite poor, and a full racing item like a gforce is going to be 3-4 times the price and not ideal for street use.

i can see this being a very popular conversion with the right kit

 

p.s ive found the quicktime item

however i want to fit it to a turbo II (series 4/5). But that bell housing requires a 92+ starter motor apparently, would it also require a change in flywheel and clutch assembly

then what about spigot sizing and input shaft length?
