when you get your box from tti. read the page about proper engine placement.
do the measurements carefully. You should have spool mounts just like my 73.
My engine sat too low in the k-member. Header tube was resting on p.s. box.
Not to mention the pitman arm and idler rubbing lightly on the headers.
My motor needed to go up to meet TTI's instructions.
the older motor mounts ( pad style ) its really easy. just add shims.
spool mounts are a little harder.
Make your motor mounts are good. do some mock ups and measure.
I left my motor loose in the k member then raised to the needed height. marked it all and redid the k- member.
not saying you will have this much trouble. But I did.
hope this helps.
