Installing a T5 conversion into my '51 AD and decided to go ahead and install a support while under there for an extra $150 and hour of work....Unsure of fit at the moment but the quality is top notch with very good welds. My needs are not critical for this item, so I am happy with what it is.

Do they make a transmission crossmember that works when you install a frame mount brake booster. The booster hang down below the frame so unless a crossmember drop below it won't work.
