75 b210 l20b swap question

[modat55]

I have a 75 b210 4 door with a14/auto and a 77 620 with l20b/5 speed.I want to put the l20b/5 speed in the b210. What will I need to modify?

I think an A10 ('78-'79 HL510) front crossmember is needed to replace the one on the B-210. This will give you the motor mounts and the proper clearance for an L20B oil pan. By the way... the truck pan won't work. You'll need a car oil pan and pick up. You will need a custom made transmission mount and a shortened drive shaft.

 

You need the pedal box from a standard transmission B-210. The '77 620 clutch master cylinder and push rod should work and maybe the hydraulic hard line and flex line from it to the clutch slave over under the passenger side floor.

 

Modify the floor hole for the shifter and add the boot.

Many thanks!! I will start my search for these parts. Know of any ?

Nope. Talk to Eric'sJB (w/e) he has an A series and may have heard of this. I think Flatcat19 mentioned the A10 crossmember.

The regular 510 (68-73) crossmember is needed for a B210. The A10 crossmember is needed for swapping in a 210.

The stock B210 crossmember and most of the steering is very very similar to a 510's, just with different engine mount towers.
