TBI 5.7L retro into ’72 questions

[DirtyLarry]

A while back I fell into a real good deal on a wrecked 85,000 mile 1990 G-Van with a TBI 5.7L and 4L60 that I couldn’t pass up. I figured I would toss this contraption into my old beater truck to give it some modern amenities such as EFI and OD. I didn’t plan on doing the actual engine swap until Christmas break but I advertized the 350/Th350 from the ’72 on CL and it sold tonight and I have to yank it out this weekend. So, it looks like I will be dropping the new engine and trans in much sooner than expected. Now I have play money to buy a TBI harness too!

My question is what are you all doing for a fuel pump to run TBI? Does anybody make a fuel sending unit with in-tank fuel pump provision for the in-cab fuel tank yet? If not, I don’t mind using a frame mounted pump on this truck even though the frame mounted pump on my ’78 with the 8.1L isn’t working so well. Any suggestions on a decent frame mounted pump for TBI?
Also, I saw something awhile back for a speed sensor in the trans that also runs an electric motor for the speedo cable. I searched but couldn’t find the thread. Who makes that gizmo?

Does the TH350 shifter linkage at the trans work on a 4L60 (700R4)?

New powertrain after a hot bath, fresh paint, tune up parts, etc.
